True story! I used to work for James "The Amazing" Randi, the famed magician-turned-arch-skeptic, at his foundation in Fort Lauderdale, where we combated psychics and faith-healers and exorcists and all kinds of predatory bullshit slingers. The reaction Mr. Randi most frequently elicited from angry believers: "What's the harm? So what if I want to believe in [magic/psychics/prayer/reincarnation/heaven/ghosts/angels]? Believing gives people hope!"
