It's totally irrelevant. Even if homosexuality were totally unnatural, that doesn't make it a bad thing.
I do think it's a combination of nature and nurture. Different for every person.
This is why I don't like these threads; we start talking about how "unnatural" something is. People are SO hypocritical when it comes to naturality. Let me just inform you with a few points.
1. You can find homosexuality in other animals and living things. Sexual orientation means very little to basically everything else. Certain species are asexual. Others are genderless. It is so dang hard
to compare humans to animals, especially when it comes to gender and chromosomes. Everything reproduces just a little bit differently, and in fewer/greater numbers.
2. Nature by definition typically has an anti-human element. I could argue that nothing is natural about being human.
3. If natural means living more like animals, and less like humans, then we would find that we are doing a terrible job at being natural. We have too much technology and advancement to be considered natural at all. Why should we start caring only about sexual preferences?
4. The only reasonable use of "natural" when it comes to humans, is that everything is natural. Or rather, humans are naturally humans. There is no specific standard. Human nature is a hard thing to generalize, especially when it comes to sexuality. I doubt there is any way that homosexuality could possibly be unnatural.
Sure, it doesn't make babies. But is that really what makes it more or less natural? I don't think so. Not at all. Nature is just another topic that people misunderstand. For everyone's sake, don't talk about how natural or unnatural something is. Even if we did find something "unnatural", we as humans don't really care anyway. Why are we only caring about this?
