Simply saying nature allows, does not refute a thing. First you must define this force, nature, that you believe in. And then you must show that there are no abnormalities in nature. Then you must show how that which you construct within your thinking, animals also construct and think the same way.Simply saying yes isn't a refutation of anything else I said you dumb Bingo. If nature allows for homosexuality, which it does, then it's natural.
simply saying nature, does not validate or prove your opinion.
