The IBA, the prior top group for boxers, said "she" failed the test and wasn't legitimate. It appealed, but withdrew the appeal. The other major player who failed a test is an obvious man with no question who didn't even bother to appeal it. The IBA is no longer recognized by the IOC because something something Russia, which means the degenerates who allowed all that drag shit is responsible for "qualifying" them. I believe its one of the only Sports where the IOC doesn't default to the International Org's decision.

The proof that it is a female is a picture of them as a child in women's clothing and their own claims. That's about it.

So either its a tranny who is getting away with a lot, or is a women/intersex that is so pumped full of testosterone and other chemicals that it basically dwarfs any other legitimate female competitor.

Both options are "unfair" to the competition. They are just trying to focus it on the "transphobia" angle to discredit the fact that the other option also looks horrible and raises even more terrible questions about doping and the chemical differences between men/women.
