Radical free speech is important and a cornerstone of the US. Yeah, you've got some real shitheads on voat but also a lot of decent people that just don't hold the previously approved PC opinions. The internet was way better before it began to coalesce into megacorps like google, fb, and reddit. Instead of defending free speech they caved to advertisers. The issue w/ that is someone is always pissed off by something and the smallest groups shout the loudest. Now we've got a situation that's gotten out of hand and even regular conservatives are targeted. Voat is basically a concentration camp for free speech online. They've rounded up all the "wrongthinkers" and sent them to one place.
Before reddit and that Mountain Dew (the hitler did nothing wrong naming contest) troll happened /pol/ was libertarian more or less believe it or not. The PC left is Frankenstein and Voat's their monster. Assholes were fewer and farther between online before they all got shipped to the same place.
When you start inventing shit like "micro aggressions" and telling everyone their racist nonstop... I could provide a thousand other examples. The left has even managed to bring back segregation on college campuses only this time they're called "safe spaces" and black only dorms.
The Radical Left and the Far Right are every bit as bad as each other and more alike than they are different. They both have a need to be authoritarian in order to stay in power. (Horseshoe Theory)
Reddit, Facebook, Youtube, Twitter, etc. have no shortage of racists. They've just got the "right kind" in our weird double-standard culture.

I think it's wrong to assume that the places that provide free speech and anonymity or pseudonymity do not reflect real people's opinions.
That they act differently in real life might just be because they're afraid to lose their job or depending on where they live may face even worse consequences.
Also in my opinion the people on 4chan or 8chan are much nicer to each other even if they use harsher language than the people on facebook, since everyone is anonymous you cannot insult another persons looks, religion, color, past opinions, sex etc. since all these things are hidden from you. You can insult groups you don't like but you cannot really insult individuals you're having a conversation with.
Facebook is pretty much the opposite. You cannot insult groups because it's wrongthink but can backtalk and bicker with individuals.
