Right, people are talking about what's spiritually natural. Talking about what's biologically natural is just missing the point. Also, why do you feel the Christian sacred texts doesn't really condemn homosexuality? I feel you have to do a lot of extra-textual analysis and theory-crafting to reach that perspective, so it's no surprise that Christians in general don't buy that idea.
It's been a while, but IIRC, the Bible only condemns homosexual sex specifically. The concepts of "homosexuality" and "heterosexuality" are modern inventions. Many ancient cultures (such as the Greeks) saw no conflict between their ideals of what we would consider "straight" sexuality and homosexual relationships. And... it also condemns masturbation, marrying foreigners, eating fish, letting menstruating women insid…
There is a very convenient Christian doctrine where there are "three types of law in the Bible", which explains that some rules are meant for Israelites and some are meant for everyone (and you [or the church] basically get to guess which apply to you).
