Every single human is born with a DNA code that specifies exactly how the organism will look, the organs to make, etc., and even certain properties of the brain which affect personality, feelings, subjective experience, etc. This is all specified in code... a woman is a human being with DNA that has certain features like producing a womb (it's a spec requirement) ... this doesn't mean every single woman is expressed perfectly according to the code, but even those that don't still have it encoded in the DNA. Until we can modify DNA in every cell, no man can become a woman, and vice versa.

Gender has a function, which is tied to sex and reproduction. If your DNA doesn't have the code to produce a womb, then your DNA will have code to make more muscles, have a larger frame, in order to protect the other sex that has a womb. It takes two organisms to reproduce, therefore two sexes, and therefore two gender roles.

We can change this and deviate from the function of evolution, but we shouldn't pretend DNA does not matter, and evolution does not matter, and all this time men and women were interchangeable. I would have more respect for the whole gender movement ideology if it was framed as transcending human evolution, but instead it's trying to rewrite it and gaslight everyone into believing the reality is not what you thought it was.
