I think it's something like this, FH: Most cultures/tribes/religions have a set of taboos, or ritual purity rules. These usually involve food and sex, and sometimes clothing, washing and so forth. Judaism, being essentially an ancient tribal religion, has a lot of these, many of them listed in Leviticus. Many Christian sects seem to have inherited this set of sexual purity taboos, while rejecting the food-based ones. I have no idea why; it seems quite arbitrary to me. These taboos are deeply and sub-consciously ingrained in our society, as any good taboo should be. I don't think most Christians are even aware that's what it is, rather conceptualizing it as a moral issue, which obviously it isn't. That is, it has nothing to do with honesty, compassion, or other fundamental moral or ethical questions. It's just a remnant of an ancient purity tradition. That's what people mean when they say things like homosexuality is a sin, or unnatural, or even immoral. It's kind of like having sex with your sister or cannibalism--on that level. So it doesn't help much to point out that there's nothing immoral about it; it's operating on a deeper, more subconscious level than that.
100% correct.
