Born this way, baby

Science shows that genetics plays a major role in sexual orientation. Science has not, however, provided any evidence that sexual orientation is a choice.

Twin studies show that genetics plays a role in sexual orientation but doesn't come close to determining orientation.

Sure, but how different is that to the standard religious line where homosexuality is entirely a choice, and an evil one at that, one that gay people opt into out of their own ignorance, or degeneracy, or obstinacy?

Yes, there's a genetic part and an environmental part. I submit to you that this is vastly different than the "choice" that the christian right wants you to believe it is.
