The US has a felon, fascist, wannabe dictator as one option and he has an honest chance of winning. Then in Germany they are having essentially a resurgence of the Nazi party in AfD and it’s been gaining traction, particularly in eastern states from what I’ve read.

I would argue that both cases are products of echo chambers rather than insufficient moderation.

I mean, those bigots don’t silence themselves when you ban them. They are still talking, just in forums that will ban you for daring to rebut them.

Because censorship creates the echo chambers that allow bigotry to thrive, censorship is a much greater problem than bigotry.
