As fluid as people wish it was, certain gender identities highly correlate with certain sexes. To be male sexually and female behaviorally is abnormal, statistically speaking.
This gender =/= sex is a recent concept invented by mankind.
The concept has only recently become popularized in the west, but the reality is not new that societal upbringing, reproductive sex, and mental self-image, while strongly correlated, aren't intrinsically linked.
That is a reality I do not agree with. Strong correlation indicates the high possibility of an intrinsic link, unless evidence states otherwise.
Below is a true story of a man raised as a woman, but unable to complete the sexual transition despite cultural upbringing, injections of testosterone and even testicular castration.
There is evidence in the form of the existence of transgender people. Some societies (as noted above) have been aware of the lack of an intrinsic link between apparent reproductive sex at birth and mental/social gender for quite a while, and analogous behavior is observed in some animals.
Just as you can't conversion therapy someone out of being transgender, David Reimer is evidence that you can't conversion therapy someone into being transgender.
Just because someone is born male, and raised as a boy, doesn't mean they'll agree once they can decide for themselves. They probably will, >99% of the time, but not always.
>There is evidence in the form of the existence of transgender people.
The link I describe isn't a link that ALWAYS holds. The link, like all links in science, is just a causal correlation.
So in short, being of the male sex doesn't guarantee that you will be of male gender, but it makes it highly highly like you will be of the male gender. That is the intrinsic connection and link I describe.
