I think we can add a “fourth” thing learned from Harry Potter - some folks will go to great lengths to condemn fictional fantasy books. Wish they had more to do...
No kidding. Books they haven't even read.
I had a friend in high school who was convinced that LOTR was the devil because it had "wizards" in it.
Then she saw the movies, read the books and realized what we had been trying to tell her.
*sigh* If these people only knew what a waste of energy it is.
