Well, I would wonder about anyone who would produce such a thing. I wouldn't commit violence against those stupid enough to do it. I would however not like to be in their shoes on judgement day.
Are you serious? Hell for insulting the "Virgin Mary"?
Hey, man, it is South Park.
I don't watch it more than once a year but of the very few times I've seen it they boil up just about everybody and every subject.
They have a keen eye for getting a point across.
South Park was not mocking either the Virgin Mary or the Catholic Church. They were mocking Alchoholics Anonymous. They were also mocking people who believe in magical healing powers.
I would imagine that if this particular episode gets much play there'll be a Moslem hit-team out to get them.
