In the hairdressers I was trying to work out why the news about Dumbledore had upset me so much. (By the way, I'm looking gorgeous now!)
I don't have a problem with Dumbledore being gay. At least I don't think I do. Do I? No, I'm sure I don't because it doesn't matter. Now, I know gay people will say that, of course, sexuality matters, and I agree that it does. And JK will say that it does matter for the character, but it can't matter that much or it would have been integral to the story. And it wasn't; it's cropped up some months later as an 'oh yes and by the way'. I think that's what has annoyed me. It seems somehow dishonest. She's said there were clues in the book but I don't think I'm the only one who's failed to pick up on them.
Over the last few years I've read Atonement (Ian McEwan) and Diary of an Ordinary Woman (Margaret Forster), and though both books were good and I enjoyed reading them - although the lead character in Diary was most unlikeable - when I finished, I felt cheated. I won't explain in case you haven't read the books, but I don't like books that leave me feeling like that. And this is a similar sort of feeling.
If it's important then it should be in the book and be relevant to the plot and be obvious. You know, have Dumbledore mincing down the corridor and calling everyone luvvie. (Some people can't tell when I'm joking: that is a joke.) If it's not, say nothing.
