Political correctness is just being politically polite. The goal is to avoid making people with different political opinions angry. 'mondays suck' and 'crackers suck' are both politically incorrect. you can hold those beliefs but if you start rubbing them in people's faces, especially an audience of thousands of people, you shouldn't be loving surprised when some of them get angry and your news YouTube channel gets reported
It's not censorship, you're just willingly pissing people off and then playing victim when those same people you pissed off retaliate. Not you specifically, but just anyone who tends to be not politically correct. The only exemption I can see in all media for this behavior is either designated forums like Reddit or standup comedy shows, like Chris rock
