Just to be clear, I don't think we should speculate about the sex of other boxers. We don't have the information.
We know Khelif and Lin are men. They probably have a DSD and as far as I am concerned, they have put themselves up to be speculated about on that score. It's not pleasant, but boo hoo, cry me a river, etc. Several other sportsmen have withdrawn from women's competitions on discovering the truth. And that's me assuming extremely charitably that Lin and Khelif only found out in 2022/3023. They could have withdrawn without admitting openly to being male.
Be that as it may, the important point is that they are men, that the IOC knows they are men AND IS FINE WITH MEN BOXING AGAINST WOMEN.
The IOC are promoting men in women's sports, not just enabling it. The public doesn't yet realise that "women" is a mixed sex category according to the IOC.
