I'm not against sex testing in male sport. The reason I predict it would mostly affect female sport is I assume the main objective for tests is to catch cheaters (people who know they would fail such a test, but enter the competition if there is no test), and obviously there isn't as much motivation for females to cheat their way into male sport as it is for males to cheat their way into female sport.
We see that in the trans issue: there is a lot of discussion about how awful it would be for transwomen having to compete in male category, while transmen seem relatively comfortable competing in female category.
Even in your example, the female enters the male category just to be treated unfairly. Why would she do that to herself, if she can enter the female category?
But this assumption might be wrong, if we think that people just genuinely don't know. Then testing everyone in both categories would be correct, yes.
Also, I think these tests should be done early, when people start competing on low level — to avoid unnecessary public exposure and painful breakdowns of sport careers in which people already put huge parts of their lives. And also for people with DSDs it's just useful information in itself to be diagnosed as early as possible, if they already hadn't until that point.
(Side note: I very much try to steer clear of accusing you of things like misogyny, bigotry etc., while you venture into such accusations repeatedly. I'd really like you to stop that, it's not constructive.)
