If having a DSD is a medical condition which makes an XY individual less physically able than typical XY individuals (men) then could there not be an argument for them to be a class in male paralympic competition. Would that be offensive to anyone?
I'm not suggesting trans individuals should be included in this way at all. But DSDs are different. I feel terrible sorry for these women who are not literally women due to something they can't control. I think they should be able to compete in sport. But not against biological women. It's not fair that they should have an advantage over biological women. But also not fair that they should have to compete at a disadvantage with biological men.
For any that have been recruited into their sport purely because they have a DSD - well, I suppose they suddenly wouldn't be interested any more in the same way that many trans swimmers suddenly weren't interested when offered an open category. But for those who really love their sport it could be a solution? And it wouldn't matter whether they identify as women, men or non binary because it would irrelevant to the competition.
