That can only happen if you gave government the ability to throw you in prison for that, and then somehow a tiny minority got into government and abused the power you gave them.

Why? The universe won't stop anybody from doing that just because laws exist. Authoritarians will not be halted by existing laws or norms. That's what I'm worried about. And that's why things like preventing fascists from organizing in public has merit.

I think this is exactly what they will be halted by. 1930s Germany was full of propaganda against Jewish people and other countries. Why bother doing that if authoritarians can just snap their fingers and force people to do things?
The Liberal state has a monopoly on violence: whatever their violence is, like throwing someone into prison, is by nature justified in the eyes of the state.
