I thought the episode on Southpark that was about Mormons was one of the best! However, once they backed down on the Muslim stuff, I lost all interest and think that their Anti-PC stance degenerated to full-blown hypocrisy. Especially after the “principaled” rhetoric for their Scientology mockery. They are exposed.
They didn’t back down. They animated Muhammad and criticized Islam. It was the network that censored that from the episodes.
