Hm...the ones that come to mind are:
Smug, holier-than-thou athiests (trust me, that makes sense).
Yinging, if it's done badly.
The Butthurt and thin-skinned. I want them gone yesterday.
Anyone who doesn't get the joke.
Badly-drawn pornography with my favorite cartoon characters in it. (Regular pornography is okay.)
Smug Europeans who also smell of body odor (other smug Europeans are simply put on a watchlist).
Anyone who lives in New England (because that place is the pits).
Oppresive anti-piracy measures.
Rabid piracy advocates.
England in general, because I just realized that they suck.
Codfish.
Fanboys. And by that, I mean anyone who unabashedly likes anything anywhere.
...I'll have more later.
