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.
I don’t see how maintaining the status quo can be seen as a “victory that makes them push for more”? That argument is much easier to push the other way:
If someone can play a sport based on undergoing X treatment, isn’t that discriminatory against those that can’t afford treatment but still identify a certain way? What about XYZ women’s only spaces, should we allow anyone that proclaims self-identifying a certain way into those spaces?
That’s the same “victory to make them push for more” just flipped.
