You do realize that there are quite a few documented case of homosexual behavior in animals, correct? So nature is now violating natural law?

Perhaps disorders might be an answer. Homosexuality could really be a disorder. People with feet fetishes have a psychological disorder that makes the brain think other people's genitals are on their feet.

Likewise, perhaps homosexuals just have the part of their brains either identifying themselves as male/female reversed (Males think they are females or females think they are males), or have their interpretations of other people reversed (they see males and females and females as males).

If a homosexual relationship isn't sexually-based though, there's no reason to call it a relationship then. It's just an advanced and close friendship. Just like straight couples.
