Many of the old default subs like News, Politics, etc are ran by the same group of moderators, and they will heavily censor things they don't like. But it's the same thing on the other side of the spectrum, a lot of the conservative subs aren't tolerant to whatever they think is "woke".
That's true if you talk about content posted on those subs. But I'm yet to be banned from a conservative sub just because I'm involved in wrong other sub.
I once posted on a sub criticizing vaccines, my post was not even friendly to the post- I was debunking flawed logic. And I got autobanned in few other places just for posting there.
