There are limitations to free speech, but the reason it EXISTS is not cover speech YOU approve it, it's for speech people you DO NOT agree with and viewpoints that aren't popular.
This is the problem I have with people who say they support freedom of speech, but when it comes to groups like ANTIFA, BLM and others on the left, it's ok to shut down white supremacist websites, but not others exposing the same thing, just on the other side of the aisle.
You can't have it both ways, that's why freedom of speech covers EVERYBODY equally.
Actually, you can, that's why there are free speech exceptions in US law and protected classes? Hate speech and hate crimes are a real thing.
Also "ANTIFA" (it's "Antifa" lol) and BLM aren't monolithic groups - one is an ideology dedicated to fighting fascism and the other is a social justice movement consisting of many decentralized local community orgs. Neither of these are comparable to Nazis literally shouting to gas kikes in the streets and running over peaceful protesters and if you think they are, you might want to check yourself.
It takes a special kind of warp to see either of those as spewing hate, whereas it is pretty easy to why people in general believe Nazis spew hate.
