Given that racists and slavers used the “natural physical strength” of black people to justify putting them on hard labor and some medics still think that blacks has higher resistance to pain, I wonder if when black athletes started to join mixed race sport teams, some racist would have used the same “biological advantage” argument that now transphobes use against trans athletes to claim it was “unfair” for black to compete against whites to justify segregation.
Possibly, though the difference in strength and endurance between a male and female is much, much larger than between two different races. Male high school athletes outperform Olympic medal winning female athletes in almost every category. The difference is stark.
Yes, that is true until you are 2+ years on estrogen and testosterone blockers, then your advantages go away.
