I didn't say that, and I don't have an opinion on that. I used sprinting as an example for a reason; the reason why women are under-represented among top sprint times is clearly biological, and I was hoping to point at the impossibility of fixing it through changing the sociological structure of track-and-field to be more accepting to women.

I think a sociological explanation for any biological phenomena has to be made up. This is why we need to have an honest discussion about the merits of biological explanations, so that we can figure out the root causes and spend our efforts effectively.
