Oh nice slide from race to geography there. Did you do it on purpose or was it unconscious bias?
The differentiator here is not the person's race but where they were born and raised.
A Black man with a DSD from a developed nation like Australia would most likey have been diagnosed shortly after (or even before) birth, but at worst at puberty when periods etc did not start, and so would never have been in elite women's sports in the first place.
A person of any race born and brought up in a developing nation without that level of medical oversight may well not have known and may have believed themselves to be a woman excelling in their sport until they got high enough up to run into sex testing. Which is, of course, why regions that have higher levels of certan DSDs and lower levels of routine medical checks are targeted by talent scouts.
But don't worry too much about our poor Australian man! He always has the option of pulling a Hubbard and simply claiming to identitfy as a woman and taking a woman's win away from her that way.
Now the really interesting question about race which you haven't asked and probably doesn't occur to you is why are so many of the actual trans women (men who identify as women without a DSD) in women's sports white?
