Polnut would have stayed had things turned out differently. But you can hardly blame him for leaving; it's almost insufferable now. Mainstream politics has embraced factlessness, so the senseless moron brigade is out in force, feeling redeemed, legitimized, and proud.

It's much uglier on the ground, I assure you. In my head I agree with Antonio, but I can't deny that my heart is with Hagrid. This place is a refuge. Some of the Trump enthusiasts here are irritating and barely tolerable, but even they are uncharacteristic, and on the whole so much better, than the larger group of Americans whom they represent.
The internet has a way of bringing out the worst in people. I imagine that most of the irritating sorts on the forum (of both pro-Trump and anti-Trump persuasions) are more congenial people in real life.
