More on that NOAA fight

I see that Science has a good, dispassionate, look at the Bates/Karl dispute.  

It confirms there is nothing harmful to climate science to it.

Hearing sounds before they arrive

I've heard about this mystery before:  how it is that people witnessing a large meteorite passing overhead sometimes report hearing sounds from it, but before any sound waves could have arrived from that distance.

A new theory as to what is happening is this:

Concurrent sound associated with very bright meteors manifests as popping, hissing, and faint rustling sounds occurring simultaneously with the arrival of light from meteors. Numerous instances have been documented with −11 to −13 brightness. These sounds cannot be attributed to direct acoustic propagation from the upper atmosphere for which travel time would be several minutes. Concurrent sounds must be associated with some form of electromagnetic energy generated by the meteor, propagated to the vicinity of the observer, and transduced into acoustic waves. Previously, energy propagated from meteors was assumed to be RF emissions. This has not been well validated experimentally. Herein we describe experimental results and numerical models in support of photoacoustic coupling as the mechanism. Recent photometric measurements of fireballs reveal strong millisecond flares and significant brightness oscillations at frequencies ≥40 Hz. Strongly modulated light at these frequencies with sufficient intensity can create concurrent sounds through radiative heating of common dielectric materials like hair, clothing, and leaves. This heating produces small pressure oscillations in the air contacting the absorbers. Calculations show that −12 brightness meteors can generate audible sound at ~25 dB SPL. The photoacoustic hypothesis provides an alternative explanation for this longstanding mystery about generation of concurrent sounds by fireballs.

Hard to believe

As noted at Axios:

A group of former senior U.S. officials from past Republican administrations have called for a tax on carbon emissions to help fight climate change, per the Financial Times. The group — known as the Climate Leadership Council — is led by James Baker, former secretary of state for George H.W. Bush and Treasury secretary for Ronald Reagan; George P. Schultz, former secretary of state under Reagan; and Henry Paulson, former Treasury secretary under George W. Bush.

They are scheduled to meet with White House officials later today, including Vice President Mike Pence, Jared Kushner and Director of the National Economic Council Gary Cohn, to present their plan for addressing global warming. They argue the proposal — which would tax carbon emissions at $40 per ton, with all of the revenue recycled in dividends paid back to the public — will "embody the principles of free markets and limited government."

Why this matters: The proposal puts influential members of the GOP on the record as favoring action on climate change — a position that is not publicly supported by establishment Republicans, as most GOP members have promised a rollback of emissions regulations now that they have control of both houses of Congress and the White House.

This is the exact policy that James Hansen (actually, a registered Republican) has supported for a decade or two, no?  I don't know whether I've ever seen much discussion amongst economists about how well it might work, but it's probably 100 times better than the current Republican policy - do nothing.

The true blockage to this ever being possible would be Republicans - including Trump - acknowledging that climate change is real, after all their years of denial and conspiracy mongering.

Can't see it happening, but it's encouraging that some Republicans - and old ones at that!* - are willing to push for it.

* Maybe I have to qualify my continual dismissal of anyone over 80 being unreliable on everything!

Stoat loses trust in Timmy

I noted recently that I hadn't realised Tim Worstall was in Farage's party and a pro Brexit-er, and as such, his judgement in anything should be seriously downgraded.

Now long time slightly contrarian climate blogger William Connolly seems annoyed to realise that Tim swallowed David Rose's article whole.

The Stoat should have paid attention to me...

Message to monty

Well, this is a bit of a surprise.  It seems to me the uber Catholics of Catallaxy (CL, db and Philippa, primarily, but some of the others too) do seem to be admitting shame about the extent of the Catholic Church child abuse issue as a result of the present inquiry. 

Yet, they still seem to hold the view that it was started as a Catholic witch hunt by Gillard, designed to hurt Abbott.  (I don't think there was ever any credible reason to believe that this was a primary - or even secondary - motive of Gillard.  But they hated her with a passion and were willing to fantasise about her evil plottings.)  In any event, it would seem that some are of the grudging view that some good is coming out of the exercise.  Quite a turnaround.

As for their insistence on celibacy not being relevant - why is Philippa, seemingly changed by her peripheral involvement in an investigation of a priest having an affair with another woman, insisting still that celibacy is not an issue at least in the case of priests having affairs with adult women??   

Could you ask that question of her?   I think she blocks emails, as she fantasises I am obsessive stalker.

Women and hair

A short article at The Atlantic gives some historical background as to why modern Western women disdain body hair.  (It doesn't cover that most recent trend, by that's been discussed a lot elsewhere.)  Some extracts:

The campaign against body hair on women originates in Darwin’s 1871 book Descent of Man, explains Herzig. Men of science obsessed over racial differences in hair type and growth (among other aspects of physical appearance), and as the press popularized these findings, the broader American public latched on. Darwin’s evolutionary theory transformed body hair into a question of competitive selection—so much so that hairiness was deeply pathologized. “Rooted in traditions of comparative racial anatomy, evolutionary thought solidified hair’s associations with ‘primitive’ ancestry and an atavistic return to earlier, ‘less developed’ forms,” Herzig writes. Post Descent, hairiness became an issue of fitness.

An important distinction in this evolutionary framework was that men were supposed to be hairy, and women were not. Scientists surmised that a clear distinction between the masculine and the feminine indicated “higher anthropological development” in a race. So, hairiness in women became indicative of deviance, and researchers set out to prove it. Herzig tells the story of an 1893 study of 271 cases of insanity in white women, which found that insane women had excessive facial hair more frequently than the sane. Their hairs were also “thicker and stiffer,” more closely resembling those of the “inferior races.” Havelock Ellis, the scholar of human sexuality, claimed that this type of hair growth in women was “linked to criminal violence, strong sexual instincts … [and] exceptional ‘animal vigor.’”...

....“In a remarkably short time, body hair became disgusting to middle-class American women, its removal a way to separate oneself from cruder people, lower class and immigrant,” writes Herzig.

As hemlines rose, threatening to reveal hairy limbs, women took extreme measures to remove hair.  In the 1920s and ’30s, women used pumice stones or sandpaper to depilate, which caused irritation and scabbing. Some tried modified shoemaker’s waxes. Thousands were killed or permanently disabled by Koremlu, a cream made from the rat poison thallium acetate. It was successful in eliminating hair, and also in causing muscular atrophy, blindness, limb damage, and death. Around the same time, X-ray hair removal emerged as another treatment option. Women would sit for three or four minutes in front of the invisible rays of a boxed X-ray machine, and the radiation would do its work. So great was the appeal of each hair withering away in its sheath that for nearly two decades women underwent dangerous radiation that led to scarring, ulceration, and cancer.

Men and body hair seems more a matter of more temporary fashion.   The 70's perception of masculinity still looks funny today, although I suppose hipster beards is something of a return to hairiness as manliness.   I'm not sure as to the average hipster's attitude to their bodily hairiness, though.    

The Turnbull problem

I'm not impressed by the Turnbull performance in Parliament yesterday:  I didn't care for the theatrical personal attacks by Keating;  I don't care for them in politics generally.  Attack ideas passionately, not personalities.  And, to my mind, seeing backbenchers getting thrilled by vitriol makes them look childish more than anything else.

I'm persuaded by Peter Martin's take on Turnbull - instead of pulling the Right into line in his party, he's trying to placate them.  I don't think it's going to end well.   

I don't care for Shorten as a performance politician much either, but I think Labor remains sounder policy wise, for the moment.

A bit nutty, Jason

Jason Soon keeps noting things said by Nassim Taleb, including re-tweeting extracts of an interview with him that have appeared at Zerohedge.

As far as I can tell, he has a general reputation of being a bit of a loudmouth quasi-contrarian, but with some basic credibility behind him.   He seems, for example, to be on the right side of climate change, arguing that the potential for disastrous temperature rise really means that action should be taken, and those to the contrary bear the burden of proving their do-nothing position.

And on economics, I have the feeling he might be more or less right (if you ignore the personal sledging of Obama) that the economic problems are not really solved:  

Oh, absolutely! The last crisis [2008] hasn’t ended yet because they just delayed it. [Barack] Obama is an actor. He looks good, he raises good children, he is respectable. But he didn’t fix the economic system, he put novocaine [local anaesthetic] in the system. He delayed the problem by working with the bankers whom he should have prosecuted. And now we have double the deficit, adjusted for GDP, to create six million jobs, with a massive debt and the system isn’t cured. We retained zero interest rates, and that hasn’t helped. Basically we shifted the problem from the private corporates to the government in the U.S. So, the system remains very fragile.

So, he worries about "massive debt".   But things start looking wonky in the second part, when he is asked how the Trump administration can address this:

Of course. The whole mandate he got was because he understood the economic problems. People don’t realise that Obama created inequalities when he distorted the system. You can only get rich if you have assets. What Trump is doing is put some kind of business sense in the system. You don’t have to be a genius to see what’s wrong. Instead of Trump being elected, if you went to the local souk [bazaar] in Aleppo and brought one of the retail shop owners, he would do the same thing Trump is doing. Like making a call to Boeing and asking why are we paying so much.

OK, he's stop making any sense. So, Taleb is giving Trump for being a non-expert who talks at a level people can understand.   The problem is - he's ignoring Trump's actual, and plain to see, ignorance on a swathe of economic and other problems, and on those matters where you can tell his general direction, Trump's approach (lower taxes, big infrastructure spend, Mexican wall, the EPA) is only going to make  matters Taleb complains about ("massive debt", climate change) worse.  Not to mention that the path Trump is taking is to decrease banking regulation - no sense of a banker punishment there;  quite the opposite.

As for Trump putting "business sense" into the system - Trump proudly pays no tax and brags about using debt to his advantage, and the string of litigation against his business conduct is embarrassing.

So yeah, sorry, but I have trouble taking Taleb seriously. 

A President for thugs

"Ha ha ha" they laughed. 

President Donald Trump appeared to quip Tuesday that he would “destroy” the career of a state senator in Texas who introduced legislation that a county sheriff doesn’t like.
Rockwall County Sheriff Harold Eavenson complained about the sheriff to Trump during a meeting on Tuesday in the White House with sheriffs from around the country. Eavenson will likely be the next president of the National Sheriff’s Association, according to The Dallas Morning News.
“A state senator in Texas was talking about introducing legislation to require conviction before we could receive that forfeiture money” from drug traffickers, Eavenson said.
“Can you believe that?” Trump replied.
Eavenson continued: “I told him that the cartel would build a monument to him in Mexico if he could get that legislation passed.”
“Who is the state senator?” Trump then asked. “Do you want to give his name?”
Eavenson shrugged.
“We’ll destroy his career,” Trump said as people around him laughed.

That trolley, revisited

John Horgan has been writing some posts about philosophy over at Scientific American, and they make for some interesting and amusing reading.   I'll just note this as an example:

Post-post-postscript: In “The Singer Solution to World Poverty,” Peter Singer uses a variation of the trolley problem to guilt New York Times readers into donating more to the poor. He asks us to imagine a man, Bob, watching a train bearing down on a child. Bob can pull a switch that diverts the train onto another track, but then the train will destroy Bob’s Bugatti sports car. Any sane person, Singer writes, knows that it would be "gravely wrong" for Bob not to pull the switch and save the child. It is equally wrong, he asserts, for us to spend on stuff we don’t really need rather than donating to groups that can save the lives of poor children. I was relieved when the Times published a letter that pointed out a kink in Singer’s reasoning. According to a strict utilitarian analysis, Bob should let the train kill the child, because he could then sell the Bugatti and donate the proceeds to a charity that would save lots of children.

A detailed take down of Matt Ridley

Yesterday I noted Matt Ridley's hyperventilating article that appeared in The Times (and was re-printed in The Australian).

Today I'm happy to link to a very detailed rebuttal of it by Bob Ward in a letter he sent to The Times.

Again, the people who should read it won't.

As for John Bates, he has given another interview in which he says he wasn't accusing Karl of fraud.

What's not yet clear is whether he has any problem with David Rose, Delingpole (a clown), Watts up With That and scores of other wingnut outlets reporting on his complaint as if it is a clear allegation of fraud.  

I strongly suspect Bates might have voted Trump - he has that carefree attitude to truth about him that indicates as much.

Update:   predictably, all the gullible Right wing columnists (Chris Kenny, Miranda Devine, Andrew Bolt) gobble up Ridley and Rose uncritically.   All so easily conned and fooled...

Motivated reasoning and the dishonest and foolish

The latest kerfuffle that climate change deniers and lukewarmers have come up with regarding climate change is the story of John Bates, recently retired from NOAA, who obviously has a grudge against those in the organisation who didn't follow his data preservation protocol before publishing their 2015 paper.

I think Rabbet Run has probably boiled it down to the basics pretty well:

• Bates designed an overly complicated set of procedures for climate data archiving.
• He got upper management at NOAA to sign on because the charts looked pretty.
• There were huge delays in implementation because of software problems and more.
• The process was a huge time sink.
• But it had the virtue of making Bates the Gatekeeper.
• Others were not happy with this.
• They had science they wanted to publish so they found a way around Gatekeeper Bates.
• Gatekeeper Bates went crying to Lamar Smith.
• Trump becomes president
• Denialists need an issue and cast about.

If you read Judith Curry's blog comments about it (one of the few times it is worth going there), you will see the straight talking Nick Stokes and Mosher repeatedly explain that Bates' complaint about data is now redundant - it is all available and has been for a long time - it just wasn't available as soon as Bates thought it should be.

Stokes notes that Bates' comments go beyond this, though, and suggest that he is not above making normal denier talking points.   But he was not directly involved in the paper, and those that were have made it clear that his claims are based on (to be generous) lack of knowledge of the work on the paper.

And besides, the results have been confirmed by completely independent analysis.

So, it is truly a storm in a teacup, and Bates' willingness to run to climate change denying politicians and journalists to make his "whistleblower" claims shows that any interest he may have in public understanding of science has been completely overwhelmed by personal grudges (and, I suspect, political views).  In fact, Rabbet Run's blog now suggests a personal motive.  

Of course, David Rose has blown this up into a full blown fraud allegation, complete with use of a clearly dishonest and deceptive graph which has misled his gullible readers who will not read anything critical of Bates' claims, and the graph gets reprinted by Andrew Bolt.

(After complaint, Rose amended the wording to his graph, but not the graphic itself.  The visual effect is obviously completely misleading and of course it does not suit his propaganda purposes to change it.)

Matt Ridley has also joined in the massive beat up in, claiming (if I recall him accurately enough) that it doesn't matter if independent work has verified the NOAA finding, it's still a huuuge scandal.   [Actually, yes - it matters enormously, you twit, and it makes all the difference as to whether the argument actually changes anything about the results.  It doesn't.]*

This whole process is what is infuriating about climate change debate - so many people with "motivated reasoning" to disbelieve that climate change is real, or serious, simply are being conned by dishonest propagandists and will not investigate enough to understand how they are being connned.

I wouldn't be so annoyed about it if it weren't for the way they are trying to take the world with them down their foolish path.

And now that I have finished this, I see there is a great article covering it up at Ars Technica. 

*   Here's the actual quote from Ridley's huffing and puffing article about politics influencing climate research - truly hilarious coming from him:

Colleagues of Karl have been quick to dismiss the story, saying other data sets come to similar conclusions. This is to miss the point and exacerbate the problem. If the scientific establishment reacts to allegations of lack of transparency, behind-closed-door adjustments and premature release so as to influence politicians, by saying it does not matter because it gets the “right” result, they will find it harder to convince Trump he is wrong on things such as vaccines.

 Stupid, stupid.   As Stokes and others notes - Bates offers no evidence of Karl's thumb "being on the scale", and if those using independent methods confirm Karl's result - then that is strong evidence that Bates' claim is wrong. 
  

When blowhards agree - they're probably wrong

After some quite extraordinary numbers for alleged child abuse within the Catholic Church were discussed today at the Royal Commission, I was reminded by Twitter that this was Paul Kelly's comment when Julia Gillard first established it:

And on the other side of the political fence (well, I don't think they ever have much in common), here was Sinclair Davidson's comment that same week:

The level of anti-Catholic bigotry being displayed is simply appalling. While criminal behaviour cannot and should not be condoned, this Royal Commission has started off on the wrong foot. Even before the terms have been announced.

 Both reactions look very foolish now, but they did at the time, too.

Scepticism on Republican tax and spend

On Flipboard, I see a burst of scepticism about the deficit increasing effect of Republican "less tax, but same or more spending" plan.

Here, at CSM, there is a "business as usual" estimate that paints a bad enough picture if things stay as they are:

Before beginning the Great Fiscal Policy Debate of 2017, it helps to know where we are starting from, and what would happen if government stayed on its present course. The Congressional Budget Office measures that baseline by assuming that current law remains in place for decades to come.  Gale and Auerbach project the fiscal outlook through a different lens, what they call a “business-as-usual” baseline.

They assume that temporary tax cuts continue indefinitely and that all discretionary spending will increase with the rate of inflation, despite the budget caps that Congress first enacted in 2011 but delayed in 2013 and 2015. They also assume that spending for Medicare and Social Security continues at promised levels even after their trust funds run out of money. They assume the economy continues at close to full-employment for the entire period.

Based on these assumptions, the deficit would more than double from 2.9 percent of Gross Domestic Product to 6.1 percent by 2027. The ratio of debt to GDP, now 77 percent (twice the average of the past half-century) would approach 100 percent in a decade and top 120 percent in two decades.

Those assumptions means this:

 And there, of course, lies the problem: If spending rises to 24.1 percent of GDP by 2027 but taxes increase to only 18 percent, that leaves a troubling fiscal gap. In 2027, the annual deficit under their assumptions would nearly triple in nominal terms to $1.7 trillion and more than double as a share of GDP.

And the final point:

That’s the environment in which President Trump has proposed a tax cut that would add $7.2 trillion to the national debt over 10 years, according to Tax Policy Center estimates. The outlook developed by Bill and Alan can provide a road map to help understand the consequences of such a fiscal policy.

At Bloomberg, a prediction is made that Republicans will simply let the deficit grow:

What scares deficit hawks like Maya MacGuineas, who runs the nonpartisan Committee for a Responsible Federal Budget, is the prospect of a deal to give both Trump and Capitol Hill Republicans whatever they want. In that scenario, House Speaker Paul Ryan would get the huge tax cut he has always craved, with most benefits going to the wealthy, and would agree to take politically unpopular cutbacks in Medicare and Social Security off the table, as candidate Trump promised. Trump would get the money to bulk up the military and build lots of roads, bridges and airports.

To make Ryan's tax cuts permanent without touching the big entitlement programs that drive deficits, Republicans would have to take the axe to other domestic spending.

Robert Greenstein, president of the liberal Center on Budget and Policy Priorities, spearheads opposition to reducing spending on the poor and working class. But he has substantive credibility and works with some Republicans. Last week he warned there are "mounting signs" that Republicans are planning "harsher" cuts than they have offered in recent years, slashing as much as $8 trillion of non-defense spending over a decade.

That would take domestic spending, exclusive of Social Security and Medicare, to about half the average under President Ronald Reagan. The impact would fall heavily on the poor.
That would probably antagonize too many voters, though, including some who supported Republicans in 2016. The way to avoid that political trap while giving Ryan and Trump what they want? Let the deficit grow.

And what about the mooted reform of a wide ranging border tax?   Well, Fox Business, of all places, reprints an article that says "it could be a $23.2 trillion headache". 

As spotted on Twitter

The conservative admiration for Putin is getting to a silly, nauseating, level, isn't it?   

As for the news today that everyone expects Bernardi to form his own conservative party:  yes, if it works as a way of purging at least some of the climate change denying, Islamophobic, culture worrying nitwits out of the Liberal Party so that Turnbull can actually stop policy compromising his beliefs, it would be a good thing.  I think....

Yet more quantum for you...

A couple more papers spotted on arXiv:

Can the Many-Worlds-Interpretation be probed in Psychology?

Shades of Aldous Huxley in this paper - here are some extracts to give you an idea:

So, his actual suggestion for a psychological test of the many-world:

Seems to be a good idea for a movie script, at any rate.

The second paper has, I think, more of a philosophical tone.  It's by Nicolas Gisin, a Swiss physicist with a lot of experimental and practical experience.  His paper Collapse.  What else? has the following abstract:

We present the quantum measurement problem as a serious physics problem. Serious because without a resolution, quantum theory is not complete, as it does not tell how one should - in principle - perform measurements. It is physical in the sense that the solution will bring new physics, i.e. new testable predictions, hence it is not merely a matter of interpretation of a frozen formalism. I argue that the two popular ways around the measurement problem, many-worlds and Bohmian-like mechanics, do, de facto, introduce effective collapses when "I" interact with the quantum system. Hence, surprisingly, in many-worlds and Bohmian mechanics, the "I" plays a more active role than in collapse models. Finally, I argue that either there are several kinds of stuffs out there, i.e. physical dualism, some stuff that respects the superposition principle and some that doesn't, or there are special configurations of atoms and photons where the superposition principle breaks down. Or, and this I argue is the most promising, the dynamics has to be modified, i.e. in the form of a stochastic Schrodinger equation.

 Actually, the paper itself reads better than the abstract.   Here's the section on many-worlds, which I find the most interesting part of the paper:

His point about the "many-worlds" interpretation meaning that the initial state of the universe had to have been "encoded in some infinitesimal digits of some quantum state" is not an objection that I had heard of before.

It's also not clear to me what he would think of Frank Tipler's argument that many-worlds actually supports free will - which I noted in a post last month.

So, the many-worlds idea continues to intrigue everyone.   Here's a suggestion: the election of Trump might be evidence we've accidentally slipped into a totally unexpected parallel world.  If it can happen, truly, anything can...

No restraint mothers

I really find it hard to believe that pregnant women would assume that any psychoactive drug - in this case, cannabis - is harmless to their developing fetus. 

If legalisation means increasing use by mothers, I suspect that this will be another part of a subtle, long term harm to American society that I think legalisation may be setting in progress. 

There may eventually be a push back.    But unfortunately, for America, the current exemplar of a drug and alcohol free life* is just about the worst possible advertisement for temperance since Hitler.

* starts with "T"

Across the universe

It's very hard getting one's head around the full implications of quantum entanglement, or even understanding Bell's results properly.  (And, I would add, it's not just me.  If you scroll through the quantum section of arXiv, you'll find a large number of physicist types who are still arguing about it.)

That said, at Nature News there's a report about a new experiment that backs up entanglement:

The latest effort to explore the phenomenon, to be published¹ in Physical Review Letters on 7 February, uses light emitted by stars around 600 years ago to select which measurements to make in a quantum experiment known as a Bell test. In doing so, they narrow down the point in history when, if they exist, hidden variables could have influenced the experiment.

“It’s a beautiful experiment,” says Krister Shalm, a quantum physicist at the US National Institute of Standards and Technology (NIST) in Gaithersburg, Maryland. Although few expected it to disprove quantum mechanics, such experiments “keep pushing alternative theories to be more and more contrived and ridiculous”, he says. Similar techniques could, in the future, help to protect against hackers who try to crack quantum-cryptography systems, he adds.

Here' more, with a particularly important line highlighted by me:

But they left open another loophole — one that is more subtle, and impossible to fully close, says Andrew Friedman, an astronomer at the Massachusetts Institute of Technology in Cambridge, and a co-author on the latest paper. Bell tests also assume that experimenters have free choice over which measurements they perform on each of the pair of photons. But some unknown effect could be influencing both the particles and what tests are performed (either by affecting choice of measurement directly, or more plausibly, by restricting the options that are available), to produce correlations that give the illusion of entanglement.

To narrow this freedom-of-choice loophole, researchers have previously put 144 kilometres between the source of entangled particles and the random-number generator that they use to pick experimental settings⁵. The distance between them means that if any unknown process influenced both set-ups, it would have to have done so at a point in time before the experiment.  But this only rules out any influences in the microseconds before: the latest paper sought to push this time back dramatically, by using light from two distant stars to determine the experimental settings for each photon. “We outsource the choice to the Universe itself,” says Friedman.

The team, led by physicist Anton Zeilinger at the University of Vienna, picked which properties of the entangled photons to observe depending on whether its two telescopes detected incoming light as blue or red. The colour is decided when the light is emitted, and does not change during travel. This means that if some unknown effect, rather than quantum entanglement, explains the correlation, it would have to have been set in motion at least around 600 years ago, because the closest star is 575 light-years (176 parsecs) away, says Friedman, who hopes to eventually push back this limit to billions of years ago by doing the experiment with light from more distant quasars. Their results found a level of correlation that supports ‘action at a distance’¹....

Others argue that although, fundamentally, the loophole is never closable, such experiments are valuable because new theories necessarily become more improbable and contrived, or eventually, end up assuming that everything in the Universe was determined at the time of the Big Bang — a philosophical view that most physicists reject. Reworking experiments to reduce and make better assumptions is therefore worthwhile, says Shalm.

Adventures in cluelessness

A bleat today from Sinclair Davidson at Catallaxy:

It does seem to me that the shared values that have maintained our society and civilisation are fracturing. The left for reasons best understood by themselves have chosen to normalise political violence and hate.

This from the man who controls a blog abandoned for years now by any political moderate* due to the aggressive, belligerent and belittling style of attack routine in threads and increasingly present in posts.   Where sexism and demeaning comments about gays, all Muslims, women and all by a tiny handful of politicians are commonplace, and the livid hatred of the last couple of Labor PM's was continually on display by people banned from Bolt.

 * all except one, who ignores my entreaties to not deem it worthy of his occasional presence.

No wonder Donald hates Arnold
