I really dont think Hayes would have lost his job for saying anything. It wasnt that sort of show.
If he had such a high moral core or such respect for religions, he never would have joined the show in the first place. The <i>first episode ever</i> was a huge dig at Christianity. It could not have taken him this long to realize that the show mocks religion. And also, I think Matt and Trey would have said he long had a problem with it.
Issac Hayes did not desperately need the South Park job. He is perfectly fine financially, and can get work elsewhere. If this bothered him, he could have left long ago. But it didnt. He didnt care when they mocked Christian (repeatedly), Jews (pretty much every episode), and Mormons (who had the exact same episode as Scientology, almost). So he doesnt really have a leg to stand on.On Monday, Stone told The Associated Press, "This is 100 percent having to do with his faith in Scientology...He has no problem - and he's cashed plenty of checks - with our show making fun of Christians."
