I am a Christian and I also hold a Masters degree in biology. I base my opinion that homosexuality, except in rare cases, is a choice rather than genetic on my knowledge of biology and natural selection. There is no genetic “motivation” for something that does not serve to increase the likelihood of producing viable offspring to insure the survival of the species. Until recently, a gay man and a lesbian woman could not produce a child together without having sex in the heterosexual manner. Therefore, a gene for "gayness" would not likely have been selected for. I feel the same way about allowing a child to determine their "gender identity" and those who chose to undergo sex-change operations. If your genes say that you are XX, you are a woman. If your genes say XY, genetically you are a man, no matter what your mind (and whatever artificial hormones you may be taking) says.

To piggyback on your comment.

When people tell me that homosexuality is not a choice, that it is genetic, I ask them to explain vegans.

Human beings are genetically omnivores, our teeth show us to be omnivores, one of our survival mechanisms as a species is our ability to eat whatever is available. And yet people CHOOSE to go against genetics and become vegans, foregoing all meats and dairy products. So again I ask them, how is it possible for vegans to go against genetics, but for homosexuals to be unable to do so?
