I try to be charitable, but...

....Steve Kates just couldn't be more stupidly un-self aware if he tried. 

Here's the shorter version of what he's been writing for years "Why won't they engage in good faith dialogue, those moronic Lefties who want to kill everything good in the world and crush us under their totalitarian heal?  They need to dialogue, so as to learn how I understand both economics (buy my book) and the science of climate change perfectly, and they don't have a clue."

The point I was trying to make yesterday is that it is all very well to be speaking among ourselves on our side of the fence but useless if we cannot force these climate totalitarians to engage in a dialogue.....There is, of course, nothing that these ignoramuses say that we are unaware of. They, on the other hand, are unaware of every bit of the counter-arguments that have been made on our side. They are certainly unaware of the massive evidence proving that they are almost certainly wrong.

When a person is so clueless as to what the "massive evidence" actually says about climate change, and is always claiming evil ulterior motives on those who he does not agree with, why would anyone try to "dialogue" with him?   It's why no one bothers engaging on the topic on the science side at his Catallaxy outlet anymore.  They are, as with their contrarian scientist heros, nearly all old obnoxious cranks who'll be dead within 20 years anyway.  Unfortunately, we can't wait that long to get into serious CO2 reduction, though.

And it's fair enough that The Conversation won't let denialists engage in comments debate anymore.  It's pointless and just as bad as it would be to allow nutty anti-vaxers free rein on the site.

Jason, it must be a residual bit of your libertarian past that the Conversation policy annoys you - and citing Ian Plimer, for God's sake.  He has zero credibility on the topic; always has.  Freeman Dyson has next to no credibility on this topic - which is one well out of his field of expertise, too.

Stop being such a sucker for thinking people with high IQ and success in one field are worth paying attention to in fields outside of their expertise.  They very often aren't.
