[1]This would not mean that all self-described homosexuals can choose. Bisexuals can choose. Not everybody is bisexual but it is clear some unknown proportion are.
[2]One gene couldn't cause sexuality anyway. It's a combination of variable factors both genetic and not. The real question now is the relative importance of different factors.
But what the OP and the above poster may fail to grasp is that most of our genes are silent and many can be activated or deactivated depending upon subtle differences in environment - sometimes seemingly randomly. So having the exact same genetic code, even if that did occur, does not mean expression of DNA will be identical.

[3]I’m not so sure you do. It is impossible to perfectly reproduce the same social environment, let alone all aspects of experience. It could be something as simple as one of them having a conversation with somebody that another didn’t if they’re near the middle of the scale (and therefore bisexual). Not all gay people are "fruity."
[4]A polygrapher I talked to said that most men who come to him are innocent and have had homosexual experiences, but most characterize themselves as heterosexual. Whether it's relevant to the charges in question or not, they almost always deny even the thought of doing something homosexual until the polygrapher tests them. Though they can still legally pass in regards to whether a case is brought against them even if they "fail" parts of the battery of questions not directly related to the allegations. One part they usually failed is the homosexual experience/desire part.
Those who would be a zero on the scale would be the only ones without homosexual tendencies under any situation, and those who are a 10 on the scale would be the only ones who are purely homosexual. Everybody else would be capable of bisexuality, even if they have a preference for one sex or the other. This says nothing of the relative proportions.
1. The gal’s a lesbian in a long term committed relationship that includes a child. She’s not “bisexual”. Her twin is in a long term normal marriage that includes a child and she’s not bisexual. *shrug*
I do see what you're saying, but we're getting hampered by ambiguity of language here. When I use the word bisexual, I mean they are capable of sexual desire for both sexes, not that they actually act on their desire for both sexes.
The problem with figuring out how many bisexuals there are is that some of both heterosexual and homosexual communities claim there is no such thing as a bisexual for political reasons.
There is also the idea that you're supposed to commit to one person in ours and most contemporary cultures, thus making it necessary for bisexuals to choose one gender or the other. It would be against their interests to be open about having bisexual thoughts or tendencies because that may threaten their current or even future relationships, causing people to question their fidelity.
Finally and probably most importantly, people in our culture often demonize homosexuality for whatever reason. Thus if somebody did have bisexual tendencies, it would be safest for them to deny their gay side, so to speak.
So the reason my polygraph example is interesting is because it highlights the fact that, within that group of people (mostly innocent people accused of sexual misconduct), there are a significant number of self-described heterosexual men who may actually be bisexual.
2. They’ve found the gene combination for lots of things yet spent millions on finding a gay gene- or combination- and haven’t got anywhere. Time to divert the money into useful research.
Some things are simpler than others. When you're talking about behavior of any kind, it's going to be quite complex. It's true that everybody has choices in their behavior, but what are the choices? Somebody who is purely homosexual in preference literally can choose between living a homosexual lifestyle and not having a sex life. Should they have to make that choice? No, because homosexuality doesn't hurt anybody. What if they were a pedophile? In that case not acting on their desires would be a choice they should make morally because their sexual preference likely will hurt others when turned to action. To be clear, pedophilia has nothing to do with homosexuality. Pedophiles can be homosexual, bisexual, or heterosexual.
3. This supports my argument that homosexuality is a learned trait.
Not if you suppose these women are "naturally" bisexual while some people are naturally homosexual or heterosexual. It would be hard to test that idea without a polygraph, and even then it wouldn't be 100% certain. (polygraphs aren't perfect, but they're more reliable than relying on somebody's honesty about such an issue, lol).
4. Obviously these guys had some encounter and chose not to be gay. *shrug*
If they messed around with a guy, and liked it, they were bisexual or homosexual. Bisexuals have a choice. Homosexuals do not.
5. Again, nice hypothesis, but not backed up by the logistics of this case
It's always possible we're both seeing what we want to see, but as far as I can tell my example strongly supports my hypothesis and your example neither supports nor refutes my hypothesis. We'd need more information than you can likely obtain.
