Then you're going to have to ban a lot of cis women athletes as well as trans women, to even the playing field. Many elite cis women athletes have bodies that are far outside the bounds of typical for people assigned female, yet they are permitted to compete without invasive questioning.

The point of my essay was not that there are literally no differences between the abilities of athletes with male- and female-assigned bodies. My point is that the assumption that male-assigned athletes will always have an advantage over those who are female-assigned is overstated and rooted in sexism.
