This is southpark in a nutshell. It's amazing how much fuel it gives to the most terrible people.
Yep.
I think it's been stated before but but that's how they work.
To me, they never try hard to make a point. They leave it to each viewer to do their own mental gymnastics to get the moral they want to read.
So yeah, it's always going to raise some 'no but actually this is what they meant'
But here's the thing, I feel it's kind of like Charlie hebdo, i show you something outrageous just to tell you 'yeah this is how the world and people are', it's up to you to figure out that 'welp it's bad'. But they're never going to reach people that are not predisposed to hear that message and thus are doing more harm than good.
And why should they try? At face value, it's racist, discriminatory, etc. and there are terrible people like it for that. It's also a source of revenue while covering themselves behind 'but those people they didn't understand that we were making fun of them'. It's a safe situation for them.
Basically it's not there to teach anyone to be a better person. It's there to make you feel good and believe you are smarter, more understanding than others with edgy humor. And it works whether your ideas are leaning right or left(ish).
It is but a pat on the back.
