Dangerosa, thanks for your reply. Unfortunately, I don’t think I asked my question very coherently. Let me try again (sadly, I’ll probably fail this time too).
I do understand that just because a man molests a young boy that doesn’t make him gay, in no shape, form or fashion. However, I wondered if do to whatever reasons that said molester chose his victim is part of why others (like homophobes) like to say it makes him gay.
Ok, that still sounds convoluted to me, but I can’t think of any other way to proceeded, so I’ll just keep forging ahead and hope someone understands what I’m asking.
So, although homophobes see this male molester as gay and he’s obviously not, the cause of that would possibly be simply due to other factors (about why the molester picked a boy over a girl) like opportunity (IE: it’s easier to gain access to a child of the same sex, or boys in general, than to the opposite – again, not because the molester actually is gay but due to his chances to be involved with the children he apparently so craves) or because of an attitude of shame.
It’s that last part that made me wonder most. If a molester is looking for an in-road to keep their agenda/true identity a secret, wouldn’t that be helpful? To cultivate with a young boy how this activity that’s being forced on him makes him gay, and of course, everyone knows this is a wicked, sinful thing to be and do. Would that make any difference on who molesters choose? And if so, wouldn’t that play right into the homophobe’s hands to be able to use that and instead insist that most molesters are gay? That was what I was trying to get to.
Probably still not there though. 
Oh, and I agree with what you said about opportunities, etc. for gay people. I definitely do not think that in this day and age they’d have to look much further than any of the rest of us do to date… work, friends, club scene, personals, church or whatever. Surely no sane person would believe that a gay person would have to prey on children because they can’t find anyone else. What a nut job the guy in the OP is talking about must be. (Yeek! Horrible sentence structure I know, but it’s late and I seem woefully inept at coming up with something better. Sorry!)
