Out of the closet and into the Fiendfyre

I'm sure that anyone who cares (and probably many of you who don't) know that J.K. Rowling has brought Dumbledore out of the closet. And, of course, there's been some negative reaction to this. I don't, as a general rule, read Harry Potter fan forums, but the one Yahoo list I'm on has had people saying that it was a bad idea for Rowling to bring sex into things. Except, well, she hasn't. She said Dumbledore was in love with Grindelwald, not "Dumbledore did Grindelwald up the butt while jerking him off with his wand." And people never seem to have the same objections to characters being "outed" as STRAIGHT. I mean, Harry himself had a crush on one girl, fell in love with another, and eventually got married and had children. I'd say we have a pretty clear indication as to HIS sexual orientation, but I guess that's okay, since it's the good one, right? It reminds me of when Eric Shanower wrote his short story "Abby," featuring the twins from The Shaggy Man of Oz. There's no hint in that book as to their sexual orientation, but Eric had Twink (the girl) get married and have kids, while Tom (the boy) had an unsuccessful relationship with another man. People complained that Eric made Tom gay, but didn't seem to have the same objection to his making Twink straight. The implication seems to be that anything even hinting at same-sex relationships is dirty and should be avoided (especially by kids), even if it's no more (or even less) explicit than something involving a heterosexual relationship. Why? Apparently primarily because some people follow religions that forbid homosexuality, and not only do they insist on enforcing their principles on people who don't hold the same beliefs, but also think that kids are going to want to imitate Dumbledore and fall in love with an evil wizard of the same sex. Or something like that.
