This goes to something I mentioned earlier in this thread, and it's an issue I have with both ends of the spectrum: I don't understand politics because I don't understand the associated behaviors, the constant all-or-nothing tactics used to push an agenda, with NO regards to their potential downside.
I don't disagree with anything you said. The Right has its full share of ignorant, paranoid bigotry, and Trumpism has brought it completely out of the closet (pun perhaps intended). But the Left has made its own huge mistakes. It has weaponized PC and Identity Politics so that it's not just about "caring", it's about attacking and punishing and intimidating and ruining anyone who crosses some line. That flies right in the face of freedom of expression, and it's wrong. It's damn sure not liberal.
It's just human nature -- being attacked will increase resentments and pushback. No doubt. And if the Left is okay with that, fine. But let's not pretend that the net result is some kind of improvement, because we know it isn't. I want to fix problems, I want to see improvements. Weaponized PC/Identity Politics fails at that.
