Those who put their trust in the facts, as opposed to those who rely on faith. A senior White House aide spoke derisively of the "reality-based community" to reporter Ron Suskind, and the meme spread rather quickly among those who don't think you can get pregnant from masturbation.
Just about anyone who doesn't like Bush.
