Just a partial list from the top of my head (not in any specific order except for number one):
1. Sarah Palin....BIG TIME
2. Any Teabagger in the crowd who gets interviewed on TV.
3. Fox News
4. Ken Ham
5. Ray Comfort and Kirk Cameron
6. The Octomom
7. Any pro athlete who gets caught carrying a gun.
8. Right to lifers.
9. Young Earth Creationists (this is definitely number two).
10. Israel boycotters. Especially, if they are involved with a university.
11. Bill Donohue.
12. Father Jonathan Morris.
13. Pat Robertson.
14. Pat Buchanan.
15. The Duggars.
16. The GOP.
17. Obama's ass kissing of Islam.
18. 9/11 Truthers.
19. Evolution deniers (see 9.).
There are more, but my mind just went blank.
I just want to add that I'm pissed off at Family Guy because in their latest episode, Brian (who came out as an atheist this year), was caught praying to God by Stewie, when he thought the world was about to end. And then, when it turned out to be an April Fool's day prank that the world was to end, he winds up going to a soup kitchen to keep a promise he made (to God).
Dammit Seth, way to offend to offend your atheist brethren.
