Absolutely, those are great examples of things that are protected by free speech. When the ACLU was at the height of its reputation, and the US at the height of its soft power, we even had things like the ACLU defending the right of a literal nazi group to stage a march. And the various death cults the US has had were also all operating completely legally.

The paradox of tolerance is largely nonsensical, because the key to a free society is free speech but stringent, and blind, enforcement against actions. Somebody can larp out with their swastikas and roman salutes all they want, but the second they lay hands on anybody - they're going to have a few years in a cage to rethink their life decisions. If they repeat this onto a third time, the key gets thrown away.

In general I think that the liberties of the worst of society work in many ways like a canary in the coalmine for the rest of us. As soon as that canary dies it's not long before your government, with its 29% approval rating, is trying to do things like ban the highest polling party in the country under ridiculous mental gymnastics that, in reality, come down to little more than 'we want to stay in power.'

I would also add that, once they do lay their hands on someone (or actively conspire to), I think it's perfectly fine to respond with heftier penalties if the motivation for it is Nazi ideology or other similar stuff. It's not a free speech matter at that point.

So you believe it should be legal to yell FIRE in a crowded theatre as long as you don't physically batter anyone?
