One thing I will say for Rowling, I liked her comment at the end of this article, where she said that she regarded her Potter books as a "prolonged argument for tolerance" and urged her fans to "question authority." Not everyone likes her work, Rowling said, likely referring to Christian groups that have alleged the books promote witchcraft. Her news about Dumbledore, she said, will give them one more reason.
OK, I can dig that.
