ok this is i think sort of right of course but no gay gene has been found... are 'gay' men genetically different than 'hetero' men? of course evironment dictates what genes get selected and a certain slight amount is due to random variation etc. etc. but there's no evidence of genetic variation....or is there? it seems to me a very askable question, just find the gay gene or the biological difference.......if there's not one it would have to be 100% socially constructed. unless trees etc. have something to do with it. so i guess until the gay gene is mapped i'm going to tend towards the constructionist side...because there's more evidence for it.

CB: Some gay and straight people might be so primarily because of a genetic tendency, while some might be so more because of social learning. There may be different individual paths to the same sexual identity, one more biological, one more social.
