But guns are, what, less than a millennia old? What possible evolutionary differences could have arisen in that time frame? No way that women and men would perform differently in competitive shooting [0], right? And as it turns out, men shoot faster, women shoot more accurately.

There's all sorts of things that have only existed for a century or two where men and women perform differently. Adaptation for one task often has effects on similar tasks, after all.

This doesn't mean men are better than women at CS! But "this field didn't exist a century ago" isn't sufficient reason to assert no differences can exist.
