Ahh, yes, because fictional worldbuilding does not have to be consistent or make sense
But you are completely missing my point: Bad token representation sent the opposite message than should have been intended. Without it, everything would have been fine. Yhe demographics of the hero group would just have been representative of the general demographics in the setting. But by using token representation in unimportant scenes, you are actively saying that certain people are only good to serve as background dressing and are not allowed to be the heroes.
