One psychologist explains hate-crime-hoaxers as follows:
People who fake crimes are transforming feelings of invisibility into a fantasy that they may come to believe is reality, says Bonnie Jacobson, a psychologist and director of the New York Institute for Psychological Change in New York City. She says a “hoaxer” wins attention by playing the passive victim, similar to a person with Munchausen syndrome, who fakes an illness to get the attention of doctors or loved ones. [emphasis added]As liberals like to "play the passive victim," it would be natural that this appeals to some of them.
Hat Tip: Instapundit.
