Let's look at online discussion norms and how South Park episodes shaped criticism towards other issues and promoted "both sides are the same" in earnest.
I hate this one so much because that's never been South Park's position on anything, even in the Turd vs. Giant Douche episode it goes out of its way to argue against this and make an
entirely separate critique about the system.
South Park, when it gets philosophical, is almost always a critique of the self and its position is very anti-nihilist. The Wal-Mart episode, Gnomes, Butt Out, etc. Shit's blatant. It's funny how hard they miss it.
Coincidentally, Always Sunny is pretty much the same viewpoint.
