Great, so we should take advantage of the fact that we have major and minor leagues and separate by ability into those. If it happens to separate by gender, so be it, but if someone is higher or lower than the average for their gender then they can compete among other people on their level.

The fact that we separate by gender in spite of how, as this thread points out, there is a large amount of variability within that category that goes against the idea that this addresses the ability gap, just shows that we're not separating for that reason, we're separating for sexual discrimination.
