Yeah, but to succeed at sport, you first have to do sport... and i believe many 46 XY DSD people usually don't recognize that they're not biological women until an age at which you may not have time anymore to become an elite athlete. I mean, i understand and agree with your point, but statistically i still find it at least "strange". I don't have a strong opinion here, just wondering. On your other point: yes, photos are clear, but we don't know Caster Semenya and her family. She says she's been raised as a girl, and feels a woman. I respect this. What i don't respect is the idea to have some sort of "right" to compete against XX women without any limitation nor treatment to reduce her level of testosterone, just because she has a vagina and was raised as a girl. This means nothing.
