Since the blogosphere seems to have developed this fixation on Dumbledore’s gayness, I guess I should weigh in on this. I have never read the Harry Potter books and I’ve only seen the movies. There isn’t much to characterize the mysterious Albus Dumbledore except that he’s asexual, fond of wearing glittery, floor length dresses, and doles out blessings to children. In other words, he’s fiction’s good version of the Pope.
I started reading The Sorcerer’s Stone, and where Harry Potter gets a Dumbledore trading card gives some brief biographical info:
Considered by many to be the greatest wizard of all time, Dumbledore is particularly famous for his defeat of the dark wizard Grindelwald in 1945, for the discovery of the twelve uses of dragon’s blood, and his work on alchemy with his partner, Nicholas Flamel. Professor Dumbledore enjoys chamber music and tenpin bowling. pg 103
Partner seems to be the key word in this intro to J.K. Rowling‘s addition to fictional gay sainthood. Arguably, partner is one of those open ended words. It could mean anything. If Rowling knew he was gay the whole time, she put it in early on.
I’m not done with the book, so I don’t know what other clues exist. Then there are the six other volumes. I’m sure the major Harry Potter geeks who have pored over every word can weigh on on this issue in more detail. As for those who only have to movies to go on, don’t you know they’re not canon? They’re simply expensive fanfics with Rowling’s blessing.
