I think you make a valid point that someone could be trying to find fairness in a difficult situation without being anti-trans.
On the other hand, it’s sports. Which is not driven by fairness, but by money. I don’t give a shit either way, as far as I am concerned dope everyone up the gills and modify everyone into super humans, it is just silly sports. But I am not the person paying or advertising.
And that is all that matters. Will the advertisers put in money, and will people pay to watch. Currently, the society of those groups of people say no.
