I don't withdraw a word of my initial statement. But I do now think it may have been incomplete. There is perhaps a fifth category, which may belong under "insane" but which can be more sympathetically characterized by a word like tormented, bullied, or brainwashed. Sincere people who are not ignorant, not stupid, and not wicked can be cruelly torn, almost in two, between the massive evidence of science on the one hand, and their understanding of what their holy book tells them on the other. I think this is one of the truly bad things religion can do to a human mind. There is wickedness here, but it is the wickedness of the institution and what it does to a believing victim, not wickedness on the part of the victim himself.
