Bruce is wrong about convergence. This convergence was a thing way back when females were starting at elite sport. In the past decade or two, the convergence has mostly ceased. The difference of 10-12% in sporting performance is a complete correlation to the 10-15% difference in male and female body (sex not "gender") sexual dimorphism. Bruce is further misrepresenting the "fear" factor. Females (XX) are NEVER a threat to the male elite athletes. This is not an issue. However, females (XX) are directly affected by XYs in their sporting field at all levels, regionals, state, national, because it's NOT just about podium positions, but about qualifying opportunities, funding opportunities, scholarship opportunities. ALL athletes wishing to compete in the FEMALE category should undergo mandatory genetic testing. No exceptions. Furthermore, intersex conditions are not "more common" in the "Global South". The difference is in proper medical expertise at time of birth, where sex verification at birth is erroneous. DSD athletes in Western countries suffered from this failure of medicine to properly assess sex. This situation has mostly been fixed in the West, and we can provide better sex assessment support in poorer countries.
