I'd be surprised if this gene - I'm going to assume that their work was good and that the gene has the effect they said it does - can explain homosexuality. It's worth exploring, but a lot of human activity simply doesn't fit into the model; there's a tribe (I've conveniently forgotten the name) where males in early adolescence give blowjobs to older youths until the older ones reach a socially defined state of adulthood. At that point, the new adult takes a wife and is, from a Western perspective, a practising heterosexual, with no sexual relations with men at all and no (apparent) desire to do so. The younger adolescents, when they reach (I think) 15 or so, take on the role of the older ones, and are similarly serviced by those younger than them.
If you want to call the new adults bisexuals who for some reason don't practice being gay anymore, I suppose you could, but I don't think the model is accurate. To me, sexuality, in humans if not in these mice, is extremely defined by cultural pressures. Different examples of seemingly aberrant behaviour - for example, in Ancient Greece - seem to say that a purely biological viewpoint is very unhelpful. I think what we can agree on is that sexuality, even considered purely biologically, is not totally defined by procreative impulses in humans. Humans are, so to speak, in "heat" all year round, which is extremely unusual (if not unique) in the animal world. I think human biology primes sexual desire in practically every individual, but the method of expression and identity of the desired object, if it takes any hint at all from biology, is almost wholly a function of cultural/personal identity.
Good point.
Well where we people are different from animals is that we have a thing called ethics.
Ethics can be defined by a collection of behaviours and expectation patterns withing a group. It's also called moral, what we find normal.
This changes slowly over time, and from culture to culture.
These days, homosexuality has gone out of fashion, it is regarded by the majority as condemnable (although it's making a comeback).
In ancient Greece, homosexuality was even encouraged in the military.
Now we need to draw a line here. It's not because you give another guy a blow job that you're gay. We are not defined by our actions.
If it's a normal thing to do in society, than you don't need to be gay to do that. You can be married and have children while being (secretly) gay, the other way around.
And then there's another thing. Kinsey found out that complete heterosexuality is a rather rare thing.
Isn't it possible that we are all somewhere on a scale from 100% straight to 100% gay, with most people sitting around 90% straight?
Now in this society, people who are close to 100% straight would never explore their gay side.
They will probably deny to themselves that they even have a gay side, out of fear to be rejected by the group.
If we didn't have these inhibitions forced on us by public opinion, our culture could be much more like ancient Greece.

What about people who go both ways? If all gay people had a gay gene that made them not attracted to the other gender there wouldn't be any bisexuals.
Read a bit back please, I've tried to explain that several times before in this thread.
