You're only a moron if you both adore Shakespeare and want to burn Harry Potter books. Shakespeare incorporated alot of fantasy and witchcraft into his stories.
I haven't read anything that suggests that anyone has advocated burning Harry Potter books. If you wish to read them, fine. I couldn't care less. But any form of entertainment which glorifies witchcraft will not be in my home. If that offends you, well then . . . (enter some real erudite Shakespearian quote here which makes my point superbly).
Just because someone has religious convictions which differ from yours does not make them a "moron."
