What we need to be doing is revolutionizing views on sexuality apart from the biology argument. It's true that biological determinism here is just as big a can of worms, a scarier one in my opinion. It may have a couple short term benefits, but it's indeed a dead end in the long term.
What we should do is prioritize the mental health of those with sexualities deemed "deviant" as healthy and normal like normal humans, but how they suffer psychological damage and mental unhealth at those who don't accept it.
It doesn't have to be biological to be okay. And people should learn reach that point of understanding.
