If we were talking Adam and Eve I could see your point. But man is fallen. Each of us is born with concupiscence, but is being tempted to sin itself a sin?

[quote:38toteti]Free will explains how one would become homosexual to me better, in that, an individual is not created in that manner and that threw certain environmental factors one would choose the lifestyle.[/quote:38toteti]
