It never made sense. Hitler (yes, sorry to go there) also thought that homosexuality was genetic, which is why it made sense to him to mass murder homosexuals.

Something being genetic/inherent has very little to do with whether it should be viewed as morally acceptable. Of course, I am well aware of how troublesome it is to find empirical grounding in morality, but it always seemed to me that sexual relationship between two consenting partners was nobody else's business, least of all mine. Choice, genetics, curiosity, etc: what difference does it make? I am about as "straight" as it comes: I for the life of me can't figure out the sexual appeal of men, but it also isn't at all obvious to me why I should be offended by the idea that there are people that think otherwise. And even if tomorrow Casanova came out and decided publicly that he is making a conscious choice to from now own only sleep with men, after decades of sexual adventures with women--well, what difference does it make?
