But this:
>Whatever it is we are pushing back against, it is not liberalism.
I agree. Much of the modern far left is the antithesis of liberal, they're strongly authoritarian... but they don't think they are. They've gotten spun around, so they think they are banning, censoring, and restricting in the name of freedom and liberty. It's nonsense, but it's something they can't see when they're in the middle of it... and worked up with their own righteous anger. Or defending against the attacks of others. Nobody thinks straight when they're being attacked.
That's a good reason to actively work on keeping HN discussion civil. It keeps the reactive reptile brains of all involved under control.
At some point the progressive movement will weed out it's toxic members and divisive politics and at that point we can make real progress with making the world a fairer place again.
