Is anybody's preferences for food or colors or music or politics completely devoid of genetic influences? Are any of those preferences totally controlled by genetics? Any sensible person will answer no and no. Sexual orientation, like all other tastes, is certain to have genetic as well as environmental components (perhaps as well as genetic components triggered by environmental factors). But let's pretend for a moment that there is *no* genetic component, and it is all due to childhood or in-utero environmental factors. Doesn't this impose constraints that are every bit as strong as if they were genetic? Does the adult who results from these influences have any more "choice" in the matter than if it were entirely genetic? So lay off the bullshit nit-picking about genetics, and just don't be a fucking douchebag hater. Or do you want people telling *you* whom you can and cannot love?
