The Holocaust and the Rwandan genocide didn't happen because of absolute free speech. Quite on the contrary: freedom of speech was heavily suppressed

Why?

That's a very shallow way to look at it. First wrong: This isn't a numbers game. A party with more people won't necessarily win. Second wrong: Not all people who are not the minority are against the minority

It's not what's happening

Let them protect themselves. Don't come in with a white saviour complex and think that you're better than them
