We are not like animals. Humans possess the knowledge to project responses to inputs into the future, to build into a society a form of feed-forward stability. Your predilections are destructive to that stability and foster the almighty state.
Some people have a deep urge to start fires and burn down buildings. We punish people for that whether it's natural or not. Same with homosexuality. They can try to not act on those urges, but those urges are natural.
The course of action to take is to try to discover for sure what causes homosexuality. I believe it's abnormal hormones in the womb. If we can correct that, we can prevent many people from living sexually dysfunctional lives.
