Not Clearly Pro or Con to the question "Is Sexual Orientation Determined at Birth?"
"The science of whether sexual orientation is biological is pretty sparse and full of disparate, mixed and unreplicated findings. So that is one reason why there is a lot of confusion about it. Because a study will come out that says 'This gene!' And then another study will say 'Oh, we didn't find that same gene, but we found this gene...'
There's sort of this idea that...if someone's gay they're gay in the exact same way. Everything is the same, so it would be the same biological origin, which denies the reality that people experience sexualities and live their sexualities very diversely. Stripping that diversity away for the sake of scientific simplification ends up providing what you might arguably call impoverished science."
