I am not a sports fan, so, perhaps, my lack of interest means my opinion counts for zero, or, maybe, it just counts for zero... but
Most characteristics (eg ability to jump high, swim fast, run fast etc etc) are (IMHO) an accident of birth, perhaps, enhanced by a bit of coaching and training. Similarly, gender is as an accident of birth (if I understand the science correctly).
In sport, the "winner" is the person with the "best" performance, so, why not just scrap mens/womens categories and have one category for "people"?
