> It’s also mighty interesting how it’s always the male division that’s open, until you happen to have a sport where women are beating men at it, and then suddenly it’s the women’s division that’s the open one! (See shooting.)

It’s actually interesting. The claim in defense is that the decision was made prior to her win. This is often backformed in these committees though so on its own I wouldn’t believe it uncritically. However, it seems that other shooting sports were split already which does support this viewpoint. The real tragedy is that women weren’t allowed to shoot skeet at the Olympics after the split. Wild that flew.

Anyway, I still agree that it looks suspicious that the sport where women are quite competitive is one where this happens. I think it might just be not looking hard enough, though.

Equestrian sports are open in category and dressage is dominated by women, eventing leans female, and jumping leans male (just looking at Wikipedia medals - no expertise here). No split there. So the premise is not universally true and probably represents each sports federation differently.
