The Potter books and movies are no threat to anyone. I watched the movies out of curiosity and found them to be entertaining but nothing more. There is no attack on christianity or overt promotion of the occult in the stories.
The Star wars movies have more religious content that the Potter series. Much ado about nothing.
Yeah, and I tried for years to make that "Force" thing work. I just stopped short of drawing pentagrams on the walls and sacrificing goats in my room though...whew!
