My female friend from Algeria is Muslim and dresses like an American when she's here and switches to colorful long dresses when she's there, with no attempt to hide any part of her head anywhere at any time, unless sometimes adding a headband of beads or small jewels counts. So that is clearly the style where she's from, not stereotypical hijabs or burqas, which means, even for someone else choosing not to go with that particular style, an uncovered head means nothing.
I don't know about the likelihood of unrelated Algerian men & women hugging in public, and I haven't seen how this person behaves or dresses outside the ring anyway. I haven't seen any particularly revealing pictures of this person's crotch or any old family pictures. I note that no such pictures have been shown here and I'm not motivated to try to find them myself. And I don't know about masculine & feminine & other forms of Arabic names or why a conveniently gender-switchable name (if it is that) would've been given to a baby.
But the reality of this case is utterly obvious even if we throw all that out.
The Olympic Committee doesn't test, so being allowed to enter women's boxing in the Olympics means nothing. The only time we know Khelif's been tested by a different athletic committee, the result was gender disqualification, which Khelif started to dispute but then dropped that and accepted the committee's conclusion. The details of that test haven't been published and no other test to confirm or refute it has been done & had its results published either, both of which Khelif could've done if such test results were in Khelif's favor. And even those of us who haven't tracked down other more obscure pictures have at least all definitely seen the pictures in the ring during & shortly after the match, and we all know what women & men look like.
It's a clear, unmistakable fact that that person is physically not a woman, and we all know it, including those who deny it. It's like Biden's mental deficiency on full public display for months/years all over again. Pretending isn't fooling anybody, you're just being absurd, just give it up. I agree with socially playing along with using the pronouns people ask for on the principle of psychosocial "gender" being different from physiological "sex", but that's not what's relevant here. For the subject of how people physically perform in sports, only "sex" matters, not "gender". And, regardless of Khelif's "gender", it's perfectly clear that Khelif's "sex" is definitely not female.
Given that Khelif began to dispute that disqualification and then stopped, "intersex who only found out about it at that time" seems more likely than just "man", and "intersex" is at least a dozen different possibilities, but the bottom line is the same either way. No matter which is the specific answer, what we do know beyond any doubt is that Khelif is physically not a woman, and it would make sense for athletic associations to block people like that out of what's supposed to be women's sports, but the Olympic Committee's decision not to do so is also perfectly within the Committee's rights. It's their sport, their event, their PR, their rules. But they, and anybody else who agrees with their choice to let non-women compete with women in allegedly women's sports, can't expect everybody else to either agree with that policy or pretend that it magically means people like Khelif aren't what they are and are what they aren't.
