The centeral problem with that line of thinking is it's really hard to both set aside "social biases" and it's really hard to seperate what's useful for getting a job done and how we currently measure thinks. Consider, in an 100% egalitarian society the NBA might end up with 1-5 women. However, a similar game in an egalitarian society might be much closer to 50-50 if the rules focused on slightly different gameplay. Ex: does making the basket 5% higher change the gender balance.

Granted, the NBA is entertainment which complicates things, but the same line of thinking probably applies to the Navy Seals. IMO, whenever you see a biased rule you need to deside if it's useful before you can view it as egalitarian.
