GC: Thoughts on xenogenders and neopronouns? Why should "male" and "female" not be defined to mean one's gender besides sex? And if gender identity is not a real thing, why do cis, trans, nonbinary, etc people exist who have an internal sense of whether they're male, female, both, or neither?

I have no wish to get into your argument with futureghost. There are more commonalities than differences in the brains of males and females. I don't buy the idea that all members of one sex have brains that are so distinctly, markedly different from the brains of the opposite sex that we can say females have one type of brain, and males all have another type of brain altogether.

Anyone who claims that

somehow the brains developed separately from the rest of the body

Has no idea how embryonic/fetal development occurs. You really think that in utero the brain and the rest of body develop separately and the brain only gets put inside the head and connected to the rest of of the body sometime before birth?

If that's the case, then all the billions of scans done of human and other animal fetuses whilst still in the womb should clearly show exactly where it is in the uterus that the fetal brain is situated when it's developing separately from the rest of the body. Tons of human fetal sonograms are available online - just do a google image search. Please do post some of those images showing us exactly where it is that the human brain is located when it's developing separately from the rest of the body.

BTW, MRI imaging of fetal brains themselves has been done successfully as early as 20 weeks. The brains of fetuses have all been shown to be inside the skulls already. They weren't found floating around somewhere else in the mothers' uteri separate from the rest of the fetuses' developing bodies.

Over the course of history, many women have miscarried or had stillbirths prior to term, and with advanced medical care nowadays many extremely premature infants are born and remain alive at ever-earlier ages. But funny thing is, no medical authority has ever reported that in any these cases it's been customary for the brains to be separate from the rest of the bodies. Or that this has ever happened at all.

Believing that brains develop separately from the rest of our bodies is as absurd as believing Noel Fielding was speaking scientifically when he depicted Bryan Ferry's head a kite detached from his body, and Brian Eno's as an orange frisbee that also served as a Greek dipping platter.
