Monty, has this convinced you yet that you can only talk to unpleasant fools for so long before it makes you foolish for engaging with them - at least if the engagement is on the basis that you think you have any hope of changing their minds?
Look, I know you like to see some good in everyone, and there (nearly always) is. But when pointing out their wilful foolishness is met with mere rudeness, disdain and a repetition of tribalism, there is no point. It is no accident that any Left leaning or even centrist commenter gave up on the site years ago.
I could go on and do yet another summary of how the blog is deeply offensive, if not dangerous, from the top down. But you and my handful of long time readers have heard it all before.
What prompts me to write this time is that I reckon the reaction to Trump at the place should be seen as a reason why no right minded person can in good faith engage with them further. There is, to my mind, simply no way to usefully engage with fools who, for mere tribalist reasons, are willing to overlook the character, behaviour and proposed policies of Trump. This is unforgivable foolishness of a magnitude I could not formerly imagine - particularly coming from anyone (as many at the blog do) who professes a Christian faith.
We know the American Right was divided over Trump, and we have to give credit to those columnists who are now likely just as gobsmacked as you and I. But the threads of Catallaxy are full of non-serious tribalists - long fooled on climate change; gullible on economics; sexist if not misogynistic; bigoted. They are not for turning - or engaging with - if they cannot see the danger and foolishness of Trump and his policies.
Attack them by all means in other ways - but the one on one engagement - forget it, I reckon.
