It is not Semenyas fault to be born intersex. But completing against females is Semenyas fault. It is flat out cheating (morally, even if weak rules allow it). The IAAFs hormone-level solution is a good step, hopefully it knocks out cheater Semenya, but its still dodges the central issue . Non females should be banned entirely from womens athletics.
The 800 is a tough event. Takes balls to win it.
