People in India were told that there was a miraculous image of the Virgin Mary floating in the sky, so about 50 of them suffered burned retinas by staring at the sun. I think we can see that religion definitely attracts stupid people to its ranks.
I sure hope no one tells them that if you hit yourself on the head with a hammer real hard, you'll see swarms of angels dancing everywhere around you. Or, more likely, that if you mail all your money to a preacher, you'll get rich. But no one would be that sadistic, would they?
