I think you're on to something. It isn't the bullies that beat up small effeminate kids that makes them gay. It's the chickenhawks that spot them, swoop in, and coerce them into the "deathstyle" that deserve the thanks for that, but of course that isn't even mentioned.
Part of the problem, I think, is the expropriation of the word "gay". It used to mean "happy" and "festive"; so there may be a benign-looking lifestyle of acceptance for the otherwise rejected.
When I first found my son dragging up homoerotic images on the computer screen (he left it there, inadvertently), he was a freshman in college, home on vacation. I sat him down and explained to him in no uncertain terms that homosexuality, far from being gay, is full of pitfalls, sadness, despair, doom, disease, and death -- that it is the most cynical and selfish lifestyle out there. He nodded some mute acknowledgment; but proceeded over the 6 intervening years to go off for days at a time.
I now know that he was frequenting gay bars, in a city 4 hours away, when he said he was just being with friends. The other day, he told us he is HIV positive. Why am I not surprised. I tried; my wife tried; but he had way too much reinforcement in the university community -- in the counseling department, in the music department, in the university atmosphere at large, and in the nightlife, much of which is conducive to "it".
It is very sad. Now, the only thing that will prevent my outliving him is the grace of God. You shouldn't outlive your kids, you know.
Am I now more accepting of homosexuality? No; less. I'm actually quite incensed over it. Do I mistreat my son over it? No, I don't think so; but I do tell him that his problem is self-inflicted, even though he disagrees.
