Horribly close-minded people, people who think the Joker or Rorschach are "really cute" and "just need a hug", overly obnoxious fangirls (of the stupid variety, I mean) and Mary-Sue writers, people who hate homosexuality, people who think that if you're bisexual you're "just confused", rap, pop, Miley Cyrus and the Jonas Brothers (although if you like 'em, I won't hate you), people who just can't accept differences, anybody who vandalizes or has otherwise no respect for graveyards and abandoned buildings.
