"Hey... let's show some Muslim fanatics in next week's episode! And maybe some Wiccans being flakey the week after that!"...
Actually, they
could have, and
should have done exactly that. Not only so they don't come off as anti-Christian, but it would add a different element. It is entirely possible they intended to poke fun at others, but from what I have seen, there is no evidence to back it up.
