Presuming that homosexuality is reproductively disadvantageous (not for the individual, but for the gene) and heritable, it would likely take a long, long time for natural selection to remove homosexuality from human populations.

In order for something to be "socially triggered" there must be something designed to accept that social input.

Until homosexual tendencies are scientifically proven to stem from a particular portion of genetic code, then I don't think that natural selection will have any part in reducing the numbers of homosexual people.

Natural selection doesn't care whether or not it is scientifically proven. If it is heritable and it has a negative affect on genetic fitness, it will likely be selected out. If it is heritable and it has a positive effect on genetic fitness, it will likely increase. If it is neutral, it will hang around until drift removes it.

My personal opinion (once again...) is that it's a preference rather than a pre-determined trait.

How is a preference different from a trait? Do you consider one to have a genetic basis and the other to be "socially triggered"?
