Gender is not a social, but a biological construct.

Male brains are 10% larger than female brains (and that's not saying that men are smarter). Men have 7% more grey matter in the brain. In the cerebellum, men have more connections between hemispheres, which means an increased ability to translate perception into motor skill and ability, recognizing a threat and acting on it. Throughout evolution, males had to perform greater physical feats to defend the females and the children of the tribe, ensuring their survivability of its bloodline. In other words, men are more agressive.

Women have 10% more white matter in the brain. They have more connections across the frontal lobes, which translates to an increased empathy, social skills and nurturing behaviours. This is essential to raising children, which women are wired for.

Hormones also dictate certain behaviors and inclinations of the genders. Higher testosterone, which males have, fuels behaviors such as competitiveness, a high sex drive, agression and providing resources to attract potential mates. Add to that what I said about male brains and that's why the majority of cops and firefighters are men, they're naturally drawn to hero roles and have the instinct to protect.

Women, who have more estrogen, have the instinct to nurture, empathize. That's why, according to statistics, women mostly tend to choose majors and jobs that involve helping others, such as psychology, nursing, child developement etc. Estrogen also results in the instinct for women to make themselves physically attractive for potential mates. That's why there's a billion dollar beauty industry and why women tend to make themselves attractive with make-up and other beauty products.

The structure of the brains of transgender women are similar to biological women. The same exact case is for trans men, their brains are more similair to the brains of biological men.

Gender is biology, that's how evolution has mapped out our survival as a species. We're animals and we're driven by our biology.
