I watch and love South Park and I contended that they've been lax in dissing Islam as a theology. I don't expect them to do what they did to Mormonism or Scientology (that would be derivative and unfunny) but this did make fun of Islam as a religion and as a culture, unlike what they did before.
And it was funny. I just hope there is a part 2. I am sure they will reference the only other time they promised a 2-parter -- when they didn't do the Cartman's dad episode.
Depends if Comedy Central pusses out.
I don't think they've been "lax" about doing that, because I don't presume to know better than they do what they want to say about it. If they do want to say something about it, they will, and the content will be theirs. It's presumptuous of us to think we should give subject matter advice to one of the most topical and well-written shows on the air today. If it's a popular subject in America, I assume they'll get to it.
I'd say the episode was as much about Americans as it was about Muslims; burying their heads in the sand and such. Stating the obvious, I guess.
