I'm gonna do zero fact checking on this but I remember reading that the brain makes up phantom pains when you burn alive even after your nerves are burnt away

100% is way overstated. Off the top of my head, eating purely steak, eggs, and bacon will have you shitting your guts out (metaphorically) due to the lack of fiber. On the more dangerous end, all your old scars will open up when you die from scurvy.

bro it's x-men

ackshually for the Chinese novels it's more like

"I activate my Nine Heavens Demonic Dragon God's Forbidden Dance of Asura's Nirvana Upon the Starry River of Eternal Samsara technique that lets me punch harder!"

Oh, and there are 5 known lions(esses?) out there that shine light on a potential need for gender studies. By that I mean 5 female lions that otherwise look and act like male lions. One of them is more famous, named Mmamoriri.

Not implying they are transgender animals, but they serve as evidence that our knowledge of gender is shaky enough to warrant more in-depth advancements. Simply writing off gender studies as some liberal grift is a disservice to biology.

To add onto the hippocratic oath argument: gender dysphoria is a devastating mental illness, and so far the only effective treatment is transitioning. Conversion camps don't work, and there isn't yet a "cure-all" drug that would make dysphoria go away. That would make a case for artificially induced PMS to be less harmful overall than gender dysphoria.

As for the "we were all female once" argument, that shouldn't really matter. Neuroscience is a complicated field and it should be of no surprise to anyone that there can be a gender-sex mismatch at birth. The only reason we even see these issues is because humans culturally separate themselves by gender on a society level. There are probably trans animals out there but we wouldn't know because they wouldn't care. Also, two of the three trans people I personally know are trans men, people often forget transition goes both ways.
