And its a belief that is impossible to argue. I have discussed this with intelligent people, and they refuse to believe that outside elements have anything to do with sexual preference. It baffles me with how little we know about human behavior, that some people can take the extreme position they know that it is all about genetics. Human behavior is much more complex than that and science refutes a real strong genetic link.

Next obvious example. Prisoners turning to gay sex when no female sex partners are available.
Ya know, I've never understood why the argument of whether or not it's "natural" has any bearing on whether or not a homosexual lifestyle needs or deserves legal sanctioning.
Mental retardation is also "natural". We legally recognize Down's Syndrome as a debilitating condition that renders the person permanently dependent on the care of others. Our laws work differently for victims of Down's Syndrome than they do for other adults; retards cannot serve on a jury, cannot vote (unless they're a Democrat), cannot be executed for a capital offense, etc. Having Down's Syndrome is a consequence of a person's genetic makeup, and cannot be a result of their own life choices.
If there's a homosexual gene (or genes), how do they get passed on to the next generation? Sure, some homosexuals procreate, but their reproductive fitness is lower than that of heterosexuals; thus, it wouldn't take long for any genetically programmed homosexual population to go extinct. Mutation rates are simply not high enough to maintain a genetically programmed population at 10%.
