I think there is more nuance to this one, Khelif most certainly was a 'girl' at birth and I would not question that she grew up entirely on the presumption she was female..
This can happen with DSD, but I think from what I can see, puberty is probably where her male biological side (XY) developed her physique which is most certainly at a point this is masuline and gives a marked advantage.
However, the IOC are tools, this is what I posted in the SC thread after people complained about claims of Wokery and the IOC:
Its a complex subject, but one that I think is fair to criticise the IOC on and seems to be fuelled from a progressive ideological stance to push inclusion where it is not able to be adequately defined/controlled.
In 2021 the IOC released their new framework for inclusion which was billed as trying to increase the number of intersex, trans and females with high hormone levels in the Olympics.
The framework effectively was for each sporting federation to apply, but fundamentally it's flawed to a point of being useless, it requires "no presumption of advantage" and requires "peer reviewed evidence to show an advantage" (which in and of itself doesn't sound too bad), however the science is so incomplete in this area it doesn't even touch the sides.
So much so, in defending the IOCs decision (
https://www.theguardian.com/sport/a...failed-gender-tests-to-compete-paris-olympics) we get some great admissions
"I would just say that everyone competing in the women’s category is complying with the competition eligibility rules. They are women in their passports and it is stated that is the case."
Adams conceded that rules regarding who should compete in the female category were “complex”, especially when it came to those who had undergone male puberty, but said it should be up to each sport to make a decision rather than the IOC.
“As for the question about testosterone and going through male puberty, we issued a framework document to all the federations,” he said. “And everyone would love to have a single answer: yes, no, yes, no. But it’s incredibly complex.
“And actually it boils down to not just sport by sport, but discipline by discipline. So people may have an advantage in this discipline and not in this discipline if they have been through male puberty or not.”
Adams added the IOC’s position was for sports to try to balance fairness in female sport with inclusivity. “Federations need to make the rules to make sure that there is fairness, but at the same time with the ability for everyone to take part who wants to,” he said.
“That’s a difficult balance. In the end it’s up to the experts for each discipline. They know very well where there is an advantage, and if that is a big advantage then that is clearly not acceptable. But that decision needs to be made at that level. “
In this exact case, the sporting federation (IBA) already followed that instruction and banned both DSD competitors (which neither fully contested) for having an advantage only for the IOC after parting ways to magically find a way to ignore that and accept them anyway.
I don't blame the athletes one bit, I put this squarely on the IOC pandering to ideologies that crumble when they meet reality head on.
