So any woman stronger than the average for women ought to also be excluded then? Again, why is it specific that trans women be excluded?
There are not and likely will not be anywhere near enough trans people to occupy a single category at a single event. Refusing to allow trans women to compete as women, like every other woman, is a de facto ban on transgender women participating in sporting events. Transgender women are women, just like tall women are women and women with large lung capacity are women. Why should trans women be excluded for being above average but other women who are above average shouldn't be?
