I am more and more amused as this progresses, given that you're only demonstrating his point.
Besides, despite the derogatory slant you place on that concept, it could be a text of significant importance on a societal level, especially since Rowling's popularity gives her an instant and sizable market base. I don't think Rowling would do that, since she's tended to fairly conventional fantasy (conventional, but fairly well-written, though the last three or four books could have used a good editor to trim the excess) thus far, and other texts on the everyday travails of an overtly homosexual person have been published. Rights must always be defended...always fought for...I fight for your rights, for otherwise, who would fight for mine? Or something like that, no?
