In answer to annavc's question, i think it Doesn't really matter whether JKR has suddenly decided Dumbledore might be gay. If kids are going to grow up to be gay i very much doubt it will be because they were influenced by Dumbledore. And even if they were gay - so what?! it's not the end of the world. Better that they be gay than a rapist or axe murderer. These religious fundamentalist Homophobes need to get their heads in order. They seem to think a person being gay is a terrible awful thing, when as far as i can see there's nothing wrong with it at all.
As for the occult thing - its a fantasy book, not the Satanic Bible. Witches don't even believe in satan, and wizzards don't exist. I remember getting into an argument with our vicar's wife once during church, we used to have a Christmas gift service where all the kids would bring toys and they'd be delivered to the local children's home. One child bought a pair of lovely plush wizzards in funky purple robes, and she shouted at me for putting them on the altar with all the other toys. And this was in the days before Harry Potter. I dread to think what her closed little mind makes of thse books. She probably made all the kids in the village burn them in a big pile.
