Casters chromosomes are XY. Which means Caster is a man. The cursory social/ medical mis diagnosis which identified Caster as a female is one issue, and one which I think many people have sympathy with.
The real issue is that Casters true genetic makeup was known from a relatively early age and deliberately hidden by South African Athletics officials, the Semanya family and eventually Caster himself ,in order to take advantage of Casters identity to run, win medals and make a very comfortable living . They all continue to lie because it is hard to admit that such deceit has taken place on a world wide stage in full view.
I have no sympathy for someone who has cheated female athletes from their places on the winners rostrum, and who has stolen opportunities from promising women athletes from equally limited backgrounds who have been denied financial and training support to achieve their dreams . And who now has the gall to repeatedly state that the reason female athletes didn’t win against a cheat was that they didn’t try hard enough.
Caster Semanya would be an unknown and mediocre club athlete had he run against other men, his success is based on beating female athletes by using the physical advantages of male pubertal development, generated by the testosterone pumped into his body by his male physiology . Those testes were hidden, but they did their job . Height, bone length, lung and heart size, pelvic development, not having to contend with the monthly ligament loosening that makes injury to female athletes more likely during their monthly cycle ………….
