Caster Semenya isn't relevant to my concerns or my arguments. Unless you're ready and willing to make a very detailed, very comprehensive argument for why her (his?) case informs my assessment of Lia Thomas, you're better off putting your effort into some other line of reasoning.
Caster Semenya is a male with the CCSD of 5-ARD. It's extremely likely that at birth and through childhood they had exterior genitals that appeared to be female. During puberty, they would have developed secondary features more commonly seen in males, as a result of the high testosterone levels. 5-ARD sometimes leads to the descent of the testes and elongation of the penis during puberty, although it is also common for genitals to remain ambiguous in look. But people with 5-ARD do not have uteruses or ovaries, and frequently don't have vaginal tracts.
That said, Semenya's GENUINE MEDICAL CONDITION is completely irrelevant to this discussion. Transgender is not a CCSD, and the use of people with CCSDs as pawns in this game is incredibly insulting and offensive.
