I think that it proves that there's a genetic predisposition. I suspect it's probably really 100%, but we have people like you who make people pretend to be straight when they aren't.
Like Rush Limbaugh...errrr. Jeff Christy.
You know less about genetics than you do politics, but I am willing to educate you on why you should shut the **** up. Let us assume, only for the sake of proving how stupid you are, that you are correct. If there is a predisposition to sexual preference in genes than that fact alone is proof positive that the entire thing is actually a choice. The evidence clearly indicates that people are able to overcome that predisposition.
If, on the other hand, sexual preference is not genetic, you are still free to argue it is not a choice.
Your option.
Guy, you support a crazy man form Texas who only served in the Congress because the people in his home town didn't want him practicing medicine.... Your politics are the politics of batshit.
If there is a predisposition, that's genetics. Yes, there are gay folks who pretend to be straight and are miserable their whole lives. There are straight guys who rape other men in prison as a form of dominance, because, hey, that's all that's available and it's that kind of place.
That said, why should anyone try to be something because of what YOU want?
