I'd always hoped that J.K. Rowling would throw in a gay character into this decade's most popular book series. And it turns out
she did.
People are saying this was dropped in out of the blue, but I actually thought that in the last book it was pretty obvious, and said so
in this spoiler-filled entry.
Up until then, though, I figured Colin Creevey would just marry Ernie MacMillan.
ETA: And the answer to the question of "Is Mugglenet still homophobic?", the answer seems to be
"Yes." They're deleting all threads and all posts on the subject -- it's creepy.
I stopped visiting that site -- even though it's the largest HP fansite in existence -- after they pushed out a poor bisexual girl for speculating that a character might be gay. I went back to see their reaction, and it's dead silence.
The people who run those forums seem to have missed the theme of the series entirely.
