And to be fair...
I've seen some stuff on the "comments" sections of conservative boards that would curl your hair. Most boards don't have a lot of control, or choose not to exercise it, over who posts comments to a blog entry or some such, and the trolls come out in hordes. Apparently the world is FULL of trolls.
Heck, the "comments" sections on "Ain't It Cool News" entries sometimes make me sit there with my mouth hanging open, hoping to God that this person is some twelve-year-old in his Mom's basement, and not a voter.
