That would include people with views about Substack too, though, right?

Oh, you're so close. The fascists are parasites: they only tolerate liberalism insofar as it allows them to spread their ideas. They desperately want to--and will--silence their opponents as soon as they wield power. They view tolerance as a weakness, and the social contract as a game to be played only until it can be rewritten.

I do not dispute that Nazis can, legally, say what they say. I don't even necessarily think it's bad that their speech is protected. But their speech should have consequences, and platform owners can and should tell them to fuck off.

Not views that espouse violence.
