Genetics of Homosexuality vs. Reproductive Rights

[Emu]

I think there's a lot of evidence in favor of the view that while genetics may predispose a child to being gay, there's a certain critical period in utero in which an imbalance of chemicals (i.e., too much or too little testosterone) could permenently affect a whole range of personality traits, from sexual orientation to identity, and may even be responsible for things like autism.

Still, the answer to this question may be something we should consider. As a society, would we be willing to accept the possibility of a greater gay population than there currently is? If the population of gay men and women increases, would that create sexual frustration among heterosexuals? (Imagine being single a world in which every other woman you meet is a lesbian.)
