It's about looking at the person and not the average or the stereotype. Women on average have less muscular strength (though more stamina), but professions that need strength, like the fire service, have long ago accepted that they should let anyone take the tests, and not assume that a candidate must be too weak because she doesn't have balls.
A lot of basketball players are black, because some African subraces are markedly taller than average, but that doesn't mean white men can't jump.
