Women were unlikely war heroes in 15th century France. Having led the French to victory over the English, Joan d’Arc was burnt at the stake. That Pope Calixtus III, later declared her a martyr (1456) did not help her at the time.
Gender is a medical diagnosis made at birth based on physical characteristics and DNA/chromosome analysis. Rarely (I have never seen a case) the DNA/chromosomes fail to match the external appearances. There are a few well documented cases of babies at birth, being deliberately or otherwise assigned the wrong sex. On the other hand, I have had patients requesting or having had gender reassignment surgery. In one case, the young person had been adopted, and, so the story went, although the mother had wanted a boy baby, she did not discover the truth until she changed the babies’ nappy. The mother dutifully raised the baby as a girl, but in her early twenties Jill requested a sex change and Jill became Jack.
Despite the promises of gender equality, gender pronouns, gender reassignment surgery, gene therapy and hormone therapy, DNA cannot be changed. Nothing can make male XY DNA/chromosomes female, nor female XX DNA/chromosomes male. DNA/chromosomes caps all, and though men looking for sex may be fooled or even choose an XY woman, XXs (formerly known as women) are harder to fool.
Yes, there is gene therapy, where a gene, a tiny sliver of a chromosome, is added to a person’s DNA to treat a specific disease. Nonetheless, this remains largely ivory tower research and all the gene therapy in the world cannot change XY DNA to XX DNA
Girl skeletons are different from boy skeletons. Girls walk differently, think Catwalk v Moonwalk: run differently, think Caster Semenya an XX who runs like a man. In brief, XX skeletons walk and run from the hips, XY skeletons walk and run from the shoulders. More on this distinction later
Feel free to choose your own pronouns. Ten years after you have died, no one will remember your name, or chosen gender. Toilets, however are a practical issue. Time to make all toilets fit for the disabled and rename them. This may create havoc on the ski slopes, where XXs already slow queues because of their congenital lack of hosiery and XYs find other outlets.
Three modern stye toilets.
XX, XY, and PC
