I am well aware of the topic and if had read and comprehended post 48 you would know that. I am also well aware of how stupid and useless the question posed in the op is, while you don't seem to be.
Then you stupidly implied that gay people don't desire to have children and you think that "matting w/ the opposite sex, that it is the only way to have children, and that it has something to do with being parents. You don't come across as the sharpest tool in the shed
The OP posed a question, you provided a link that says "existence of such a gene simply doesn't exist." Then goes on to say: "That doesn’t mean such a gene will never be found" according to the video attached to your "post 48" no one really knows.
Therefore I can pose a thought that IF homosexuality were to be entirely genetic, then the person with that particular gene or set of genes COULD have no interest at all in the opposite sex and would not or could not procreate normally. That would most certainly mean that homosexuality would not be favored in nature.
If that supposition is ignored then homosexuality must be a product of environmental factors so homosexuals are created by other humans by either stressing the mother (as stated in the video in your link) or other stress factors. Also, we already know that some homosexuals are active in recruiting young children at the outset of their hormonal surge.
Your answers are laced with vitriol and insults so, apparently you won't discuss the truth or even postulate that homosexuality may not be natural at all.
