I'm Hoping to Be Excommunicated Next!

I'm doing a school visit in CT tomorrow and have just heard from the teacher of one of the classes I'm visiting that a very religious student will not be able to attend if I read anything about magic, um, I mean witchcraft. Oy. Now I have sections I can read that have no magic in them at all, but I don't think I'll be able to talk about my books much if we have to keep steering the conversation away from magic. Magic is what my books are about.

Why are so many religions so terrified of...
