The awful thing is they don't even see what's wrong with what you just described.
Extreme left and extreme right are both pieces of shit in my opinion. I'm not a centrist, but I'm not an extremist either. I just want people to not be put in concentration camps because of who they love or what they said online.
I guess it's just too much to ask for from some people. Well, at least 20 million of them.
America's left is what you describe as the far-left, but the far-left is much the same as it is everywhere else, Marxists and Anarchists. The far-left is relatively consistent internationally because its built on centuries of theory and practice.
