**Let's not beat around the bush. Homosexuality is a behavior. When that behavior is engaged in one is a homosexual. Before that point, one is not. If one gives that behavior up, then one is no longer a homosexual.**
And this behavior of homosexuality is a choice! (Just like chastity is a choice!)
As a male, I have a natural, genetic proclivity to have sex with females. This doesn't make it moral for me to go have sex with every available female.
I must control my tendency....it is a choice.
Therefore, even if homosexuality were genetic, which it isn't, then there still would be no argument for it since the behavior itself is so destructive of the human body -- solid evidence that it shouldn't be engaged in.
