I see.
Sexual preference and gender identity is likely (though strong evidence is many years off) set before birth. The environment itself might be a factor in setting this, as well as random mutation. The bovine study should a significant increase of homosexuals cows in larger herds compared to the same number of cows based in multiple smaller herds.
Post partum, society will start to either enforce or attempt to alter those preferences. For centuries homosexuals would have presented themselves are straight, because of society influence, while those whose genetics follows the social majority would have been conditioned to see deviation as against proper society.
Now most of us live in a more liberal world where our actual genetics predisposition can be expressed. While I have little doubt, some young people would be influenced into saying they're of a preference they're not biologically predisposed to in order to gain social grace (look cool) such actions will rectify themselves in adulthood.
It is the idea that "breasts and womb" means you're a woman, is socially constructed. Its not just a product of a descriptive language, but ingrained into our understanding of the world. And for the vast majority of cases this definition holds true. However to say a member of the Hominidae family with a tail can not be human, is incorrect as humans are born with tails.
The reality is that things are more complex, and as a species we're now only understanding that complexity.
Dalthnock: Funny how people are cool with sexual predators having easy access to women & little girls, but can't stand the thought a thread they don't like being open.
It's nice to see what's really important to some people.
No one on this board has every been happy with the idea.
They believe, and with evidence, that the restricting the rights of 0.3% of people will have no effect on the safety of those people.
As I said, your Adherence to this belief is like thinking a "Keep of the Grass" sign would stop a burglar cutting across the grass to get access to a house.
