The evidence for an inborn sexual instinct is as plentiful as that for the spherical earth. Yet the Bible thumpers amongst us will never accept either a spherical earth nor inborn sexual preference. It's all a deep dark conspiracy run by Satan to turn folks minds away from the absolute truth the Good Book.
Well, baloney. Sexual preference is whatever it is. Except for the Bible telling us to kill homosexuals, no one really gives a rip whether they're homosexual or not. What of it? Big deal.
Therefore, the fundies must crucify you.
