I remember reading back in the 70's a study of rat homosexual behavior versus population density showing some correlation. It could well be that {something} is influenced by hormones rather than genes. This would also account for the lack of any identified "gay gene" while still falling into being a fact of birth and not choice.
Of course one could also correlate numbers of gay people with population densities where they live, but this is obviously a false correlation due to the mobility of people within the population.
One also wonders if the historical data is not truly representative. Certainly it was more visible in any ancient cultures where it was more acceptable behavior.
