We can observe and measure physical performance objectively. Stating that the best male runners are faster than the best female runners as measured in time to finish is a demonstrable, objective fact.
Extrapolating that fact to be a significant input for how we run our society is a different matter.
Stating that men are more obsessive than women is as valid as stating that women don’t know how to take a joke, or assigning any other emotion based value to a specific sex.
