Whats up with magic and some Christians?

Those Christians I think are too worried about the labels on things rather than pay attention to the actual story. Example--Chronicles of Narnia is actually biblical symbology-- the reason people didn't fuss about it is because they were up front about saying so. Example--Harry Potter fights against evil and there is somewhat of a moral story in each volume, but since the words magic and witch show up and rowling didn't come forward and say "I love Christianity", people are afraid of it.
