If you're talking about America in this point - the US always had and still has its own weird point of view about "freedom of expression". They even allow those people to be who would dare straight abandoning the very core of their supposedly "free" system.

If you ask me about Anti-Fa, I don't have a really much high opinion about these guys these days. What does their association do? Plundering, setting poor-people-like-you's cars on fire, turning the town into a battlefield just for fun, and when the rally's over, they leave again - leaving behind the remains and ruins for all other people, the community, to clean up again.
These clowns - I find, you don't even need to be far-right just to oppose them and to reject their presence on events that you hold or support.
