It's one hill I am prepared to die on. Every sport is/was divided into male (born), and female (born) categories to ensure fairness. This was based upon the biological reality that men are taller, stronger, have bigger longer limbs, bigger hearts and lungs, can run faster and longer, and if only one category was present, only men would win, ever. So what would be the point if women entering sport if they had no chance of winning, ever. In golf, in particular, women's clubs are shorter, the tees shorter, their handicaps greater.
This biological reality has not changed.
Why do disability sports spend so much time putting competitors into different categories. To level the playing field. To make it fair. Imagine the uproar if someone pretended to have a disability that the did not in order to game the system.
