No, it's because he is respectful of other people's beliefs and doesn't write something simply for the controversy.

Example: the episode of The Simpsons where Homer becomes a heretic; Homer is not saying anything controversial. In fact he's saying things that many (if not most) religious people have thought at some stage or another (I'm not a bad guy! I work hard, and I love my kids. So why should I spend half my Sunday hearing about how I'm going to Hell?). And the episode ends with Homer getting a good lesson on the importance of religion:
Ned: Homer, God didn't set your house on fire.
Rev. Lovejoy: No, but He was working in the hearts of your friends and neighbors when they came to your aid, be they Christian, Jew, or ... miscellaneous.

So I fail to see how there is anything there that anyone should get upset about. Now, If The Simpsons had an episode where they showed Mohammed breakdancing and singing a song about how all Muslims are suicidal hypocrites, that would be a different story.
