Well, literal Nazis would be a good start.
The problem is that most of the blocking is simply because people don't like the speech. This is a huge concern for any liberal democracy. Free speech is a right, and that means speech that one doesn't necessarily like!
Not correct. It's a human right regardless whether you believe it or not. https://www.un.org/en/chronicle/article/freedom-expression-fundamental-human-right#:~:text=Freedom%20of%20expression%20is%20a,Universal%20Declaration%20of%20Human%20Rights.
Just because America doesn't allow free speech on their social applications doesn't make it right. Pull your head out of your arse. Yelling fire when there isn't a fire isn't an example of free speech you moron! We're talking about political free speech.
