It's always struck me as odd when people handwave trans / nb people by appealing to this immutable structure of "basic biology". At one point, it was just basic biology that you would die of cholera with no recourse. After all, you're supposed to die of some random ass disease. If you're short sighted, basic biology would leave you with severely impared vision.
Humans have the capacity for self determination through technological intervention and medical science.
no you can't carry extra seeds and berries back to your tribe to feed your family, baskets go against basic biology!
"Basic biology" is the enemy, always has been. Anyone who denies this will suddenly change their tune once that sacred "biology" is a cancerous tumor growing on their body requiring surgical removal and chemotherapy. TERFS and their ilk like to accuse people of denying the objective biological reality of the gender binary, as if we can medically intervene in any other biological process but this particular one is beyond our reach and will always remain that way. These people lack ambition: “If nature is unjust, change nature.”
