You know how sometimes you walk up on a conversation and hear just a small part of it and it totally gives you the wrong impression? I just over heard the phrase "he's confused about sex" and then "but, we're a nation that's confused about sex."
Apparently, the parents and religious types who are spinning their wheels railing against Harry Potter (full disclosure: I've read every one of the books) rather than rearing their children are having a circle jerk over the news that Dumbledore is gay.
I'm not quite sure how anyone would guess him gay - it isn't like any of the adults in the book were actually sexual in any way. Well, I take that back - one of the professors does have a romance with another non-professor - marries her, and they have a child. We can assume that "sex" was the originator of the child. There is also some student kissing from time to time - but we are talking teens. But, for the most part, the books are refreshingly devoid of sex.
And, if I'm not mistaken, all of the characters are FICTIONAL.
There are old people cutting their pills in half because they can't afford the full dose of their meds. There are children going to bed hungry. There are monkeys hiding amongst you. But, yet, you worry about the supposed sexuality of a fictional character? Ever hear of priorities people?
