The Christian argument, as perhaps first posited by Paul in Romans 1:26.27, is that same sex sexual activities are, "contrary to nature."
I'm pretty sure Paul's "contrary to nature" comment was directed specifically toward those who had an established inclination, "natural use" toward the opposite sex. Paul did not say homosexuality was contrary to nature. He said that violating your own sexual orientation so as to engage in other sexual activity was contrary to nature.
If you read the entire context of this passage, you find that all the things listed, including unnatural sex acts, were being performed as religious rites.
This was not a broad condemnation of HOMOSEXUALS, rather, it was a condemnation of a bunch of perverted HETEROSEXUALS.
