I think there's room there for the peer reviewed science to let sanity back in eventually, assuming researchers are allowed to study the topic. But the burden of proof should be on those wishing to admit males into the female category not those wishing to exclude them because of sexual dimorphism.
We need a female Olympics if this shit continues. It doesn't matter if it is a proportionally small number of men prepared to cheat, you only need three worldwide to exclude females from the podium in an event.
And we know there is huge pressure on countries and athletes to exploit any advantage to get medals.
Recentish BBC documentary on The Unfair Games looked at problems with the Paralympic categories that allowed unfair competition and how ruthlessly it is exploited because of intense competition.
DSD mean that there are already issues within the Olympics, but allowing self identifying into the female category completely irradicates it.
