But again, the female leagues were established because of the physical differences between men and women. Yes, some trans people who undergo some medical interventions have some of their physical sporting attributes brought closer into line with the opposite sex, but it’s not all attributes and it’s not all athletes. It’s exceedingly complicated.

The reality is that female leagues was a cultural hack that worked well enough in the 20th century. But in a world where we recognise that neither sex not gender fit neatly into binary categories, it is impractical to assume that we can fit people into two sporting categories.
