Why Is The Progressive Left So (a) Obviously and (b) Radically (c) Wrong about (d) Everything?

This is not normal. As much nuttiness as I've seen in American politics and society in my lifetime--usually more on the right, it seemed to me--I've never before seen anything like what's happening on the progressive left. Being wrong is one thing--in many or perhaps even most ordinary cases, errors are excusable. But the more obviously and radically you are wrong--and the more things you're wrong about--the less excusable...and even explicable...your error becomes. 

   My general explanation has long been political correctness--a general tendency to subordinate truth and reason to (leftist) political dogma. This is tightly associated with attempts to squelch disagreement/speech. Squelching disagreement is one of the surest routes to error. And all of this is tightly bound up with dogmatism, i.e. the refusal to honestly assess one's own and one's own party's beliefs and acknowledge error. My guess is that all this set up the situation we currently see on the left: a snowballing of crazy.

   This is not normal. And it's not going to be ok. 

   By that latter I don't mean that we're doomed. What I mean is: there is insufficiently good reason to think that this is all going to work out. If you think you can just opt out and rely on things to fix themselves, you're deluded. Fundamental planks in the insane platform of the progressive left are being built into government and society. Even if things were to start to turn around tomorrow, some of those planks are going to be hard to remove.

   To repeat: this is not normal.
