Thanks for the clarification -- I was going to post it.
I tend to think in terms of the nature of the criminal violations, rather than the speculative matter of the perpetrator's orientation. The Spacey story reminded me of my own rape. However, my rapist conveyed to me that I was a one-off, that he was straight. I can't say that mattered one way or another to me. He might have been lying or telling the truth, but the salient facts are what he did to me. He's welcome to take the matter up in therapy, but it's nothing to do with me. I also know a woman who was raped by a guy who lived and died self-identified gay. The issue in both cases, as well as with the instances of child-rape with which I am familiar, is male sexual predation. In my view, muddying matters to serve a homophobic agenda is beyond un-helpful, it is actually damaging, tacitly suggesting that raping women and girls is more Godly. 

I sincerely hope we see a bunch of men go to prison for this stuff.
