Do you think Trey Parker and Matt Stone really...?

Toned down their level of satire for The Book of Mormon" (the musical)? It seems much tamer than what they did for South Park? (BTW - I have nothing against Mormons - I think they are the nicest of all fundamentalist Protestants! I accept without rancor that they disapprove of me as a secularist. But none of them has ever been rude to me. Besides, Mormons have the cutest guys. Clean as a Marine!)
