That's an evolution 101 explanation of why heterosexuals are not extinct, which is fine as far as it goes. It's not a causal explanation of what makes people straight. In fact, no-one knows what makes people straight, gay, or otherwise. So there is not much to talk about, from a purely scientific point of view. But anyway, that was an aside. You haven't responded to the main point of either of my comments. If you really are only interested in having a debate about the causes of homosexuality, I'm not the person you're looking for (and the comments on this article aren't the place for it).
