Because of the recent events in Sky's life, I'd been hesitant to answer this before. However, here goes.
First let me say that I don't think that the title of biological v. choice covers all ground. For some people, I don't think that it's a conscious choice but things may have happened in their lives that drive them one way or another. In other words, sexual attraction to the opposite sex may not be a conscious choice for someone but that doesn't necessarily mean that they were born that way.
In fact, this concept of being born that way is a very recent concept. What little research there has been on this topic which claims to "prove" that it's biological has focussed on members of the same family, who are very likely to have been subjected to some of the same environmental factors, and nobody has managed to find any difference in the DNA of those, who identify themselves as homosexual and those who don't. Oh, there was one study that did show a difference but it limited its study to people who were HIV positive and it was later discovered that all HIV positive people, gay or not, had the same marker in their DNA.
Now, as far as homosexuals saying that it was a conscious choice, most people are probably not old enough to remember a program called "Playboy After Dark." Even if you are, it didn't last very long because it was on very late at night, it was very boring, and almost nobody watched it more than once.
I happened to watch it once. It just so happens that the program I watch was a documentary on the homosexual community in San Francisco. I don't remember how long ago this was but I do know that the term, gay, still meant happy then. Anyhow, they interviewed several people, both men and women, from the gay community and all I remember the women saying was how women were much more tender than understanding than men.
However, at least some of the men said that they had left heterosexual relationships because they didn't want the permanence that women seemed to want and, as AID hadn't been discovered yet, what man wouldn't want nonstop sex?
Also, let's remember that, from a religious viewpoint, it's not a question of what one might want to do but what they actually do. Most of the very same people, who claim that homosexuality is biological, also claim that being a sociopath is biological. In the latter case, does that mean that, since they didn't make a choice, that they bear no responsibility for their behavior? I think that you'd agree that would be absurd. So, if having sex with a member of the same gender is immoral, does whether or not you're more attracted to members of your same gender have any relevance? In other words, does nature control morality? The answer is no.
On an earlier post, Skylark wrote: "
To me it is WRONG to establish that sexual preference is emphatically a choice IF it is not true."
Isn't it just as wrong to say that it's not a choice if it is true?
In any case, I don't think that it really matters. I know men who admit to struggling with same sex attraction. I don't judge them nor do I consider myself any better or more moral than they are. For that matter, I struggle with doing things that I know are wrong and not doing what I know is right. In other words, I sin. However, it's one thing to sin. It's quite another to flaunt it in people's faces and say that you're doing it because you have no choice. As far as the attraction itself goes, you may or may not have a choice. As far as the action goes, you most certainly do.
