I am sure scientology is nonsense but they are a pretty easy target. If South Park really wants to show a little courage, let them ridicule Islam let's see... a gay Saddam Hussein... Osama Bin Laden as a nut job cave dwelling cabana boy....
they get around to trashing everybody...
Attacking Saddam and Osama is about as safe as it gets. Lets see them do one on Muhammmed.
Maybe they have, I don't watch it very often.
