Dumbledore is gay!?

So J.K Rowling has stated, in answer to a fan's question, that Dumbledore is gay.

I believe this neatly delineates one of the central cultural questions of our day, to whit: what exactly is the essence of homosexuality? Is a person gay because of something in their nature, or are they gay because of their behavior? The answer to that question lies behind the entire cultural war. So I find it interesting that the most successful fictional series of our time provides such a compelling answer.

How does Rowling's response answer the question? Just this: You see, Dumbledore never exhibits a single gay behavior throughout the entire series (I know, I've read every book multiple times). He is only gay because Rowling imagines him to be gay. I believe this is the same for the vast number of homosexual men (women too, to a lesser extent). However, the facts as expressed in the series make the point in start terms. Since Dumbledore does not exist, he cannot actually be anything, except what the author says he is. His homosexuality exists entirely in Rowling's mind.

This is not to lessen the realities of real, live homosexuals. It is just to say that there is an interesting statement about the thought processes of a culture when the statement of J.K Rowling is taken as having any meaning whatsoever.
