South Park is a really hit and miss show, and a lot of that comes from the one week process. Whenever Matt and Trey come at an idea that they don't really know and try and throw something together, that tends to be their worst episodes. Their Inception episode is an example, where they didn't even watch the movie and instead listened to a third hand description. They're better at stuff when they have time and motivation and are willing to put in effort, but South Park is this weird example where it was a super shocking episode in the 90's, but now is one of tons of cartoons meant for adults, which kind of pushes against the PC argument. There are more of these shows, not less, and people can talk about them and why they can be good or bad, the thing here is they created a character that's inconsistent at best, and representative of a group that doesn't really exist at worst.
But I'd like to reiterate there's not really a push for safe spaces, whatever the term means, outside of a push by Conservative groups who actually say bigoted or falsified things and get upset when people push back. Is it really wanting a safe space to want someone who posts bigoted garbage on a site that explicitly says it doesn't want that in it's ToS? We have actual data that White, Christian people believe they are the most persecuted group in America, and anyone outside that group will just laugh about how blatantly false that is.
If a group has more power than another group they hate to admit it, because then it means in some way you had some natural advantages, so it gets put into their head that no things aren't that way it's all me, and when faced with the reality of the situation get into their own bubble instead of dealing with how things actually are.
