I think this illustrates the opposite point: that being of the female sex is the most important eligibility criterion for ensuring fairness and maximising safety in women's sports, and identity is irrelevant to this.
No but the commenter I was replying to suggested removing both sex and identity as eligibility criteria for women's sport. Whereas I was arguing it should be sex first and foremost.
Additional criteria can be added to take care of the edge cases but sex is most important and impactful.
