How this athlete was raised and what this athlete believes is irrelevant.
YY.
Also, IcelandicYoghurt, Caster does not run "unusually fast" for their sex. Competing against XY people, they would even not be at world class levels, and would be bested by many high school boys.
The entire 800m women's podium in Rio was dominated by XY athletes. Does a lack of proper medical diagnosis at birth or in early childhood make it just to deny podium finishes to women in the women's category - podium finishes that for those women can mean opportunity, sponsorship, income, and yes, actually being an Olympic medallist. I know my answer to that.
