Are you aware of intersex people? This is why the editors of Nature are correct in saying the proposal has no foundation in science: https://en.wikipedia.org/wiki/Intersex How do people with ambiguous traits at birth get categorized according to such a proposal?
"For 99 percent of us, our sex and anatomy dictate our gender; they are essentially the same thing. But for the one percent of the population who are transgender or intersex, their sex and gender don’t align. What has complicated this issue is that some outlets have replaced the word sex with gender when reporting on the memo, particularly when making any references to anatomy."
"But intersex people possess both female and male anatomy, which leads to having a gender identity that may be different from the way they appear to the outside world. To suggest that this group proves that gender is completely unrelated to anatomy, or that a person’s sense of gender in the brain somehow operates in a way that is distinct from the rest of their body, is foolish and erroneous."
Where would you put someone born with male genitals, but who identifies as female, and for whom brain scans show a brain that has female hormone responses and female processing patterns, who undergoes male to female sex reassignment surgery?
