In fairness, should you be genuine, I don't think it's that surprising that people are still under this impression.
Semenya and his team went to extraordinary lengths to propagate the notion that not only is he female, but it was an absolute scandal that people were questioning it.
It was called racist, on the basis that people think black women look masculine. He was called a woman with naturally high testosterone. He was almost a victim of sexual assault, because he kept having to have his genitals examined, etc.
When it was first discussed on this site, the majority of posters genuinely thought he was a woman and were as scandalised as everybody else about the speculation. It looked like a feminist issue.
But gradually, the evidence piled up. Past photographs, past interviews with coaches, etc, his own interviews, the fact that no woman has as high testosterone as a man, and the fact that he looked and behaved exactly like a man. Not a masculine woman, a man - who thought women were 'soft'.
Then someone mentioned that this particular DSD resulted in a micro penis which could easily be mistaken for a clitoris, and an F on a birth cert. And that scouts routinely searched out boys with it and it was known colloquially as penis at 12. Which indicated it was a very well-known phenomenon indeed.
Then, it was confirmed, that he had a DSD which is male specific, and very well understood.
And then of course, the absolute bat shit statement that his testicles don't make him less of a woman, sort of put the lid on it.
But I certainly remember, his PR machine being very successful indeed in the beginning.
So I'm not surprised that some people still don't get it.
Hopefully, @Uglydumpling you do now.
