Do they support free speech? Do they support your right to peaceably assemble?
Just another American tribe that sees itself as some sort of savior to the oppressed and who thinks their end justify their means.
2021 America craves the proud boys and antifa.
They literally do all those things. They support protests by people who are often under threat. They counter protest against known violent extremists. I'm not saying they're perfect but your questions are disingenuous.
Dressing in black (blackshirts), marching down the streets, beating the perceivably "wrong" thinking civilians, demanding end of democracy, suppressing free speech, etc.
When half of America sees a fascist under every rock, but doesn't even know anything about real fascist and fascism from history books.
