Let me turn this around and see if it makes sense to you.
There is NO evidence heterosexuals are born that way.
Anyone on the FR want to try and support that theory?
You keep missing the point. Homosexual radicals and their sympathizers insist a gay gene exists. Science disagrees.
So what? Does that have any bearing on the conversation, you earlier argued that it doesnt matter if homosexuals are prewired or not, ACTIONS are what matters. So I don't see why you would care whether or not a hetero gene exists. If it doesnt, then it all boils down to choice for everyone doesnt it. We perputuate humanity by procreating with the opposite sex. Regardless of the straight gene or not (I have no idea, being that I am not a geneticist or excitedly searching for the answer daily) HOMOSEXUALITY is a choice. They choose to act on impulses, that fact is not affected whether or not there is a straight gene.
