It seems like you are just dancing around with the definition of "equal capacity" so that you can say things that seem to contradict the points discussed, while not contradicting them, but also not admitting that they are correct. There are women that are just as good marines as men, and there are women that are just as physically fit as men. However, despite this, it's entirely possible that statistically fewer women pass. You haven't denied this empirical data nor tried to argue that it is purely for cultural reasons that fewer women can pass these physical fitness tests. So it's possible that fewer women end up in a profession for purely biological reasons, you are conceding? Similarly, it's possible that there are women (many women) who are just as good or better programmers than many men, and enjoy it just as much and are equally capable. But, that when you look at the averages, fewer women prefer it. Then, part of that relative difference could be explained by biological factors. Again, this is not a complicated argument. There's no evidence to suggest that biological factors account for 100% of the gender gap in developers but there's also not much evidence to suggest that any factor accounts for 100% of the gap. It's likely to be a combination of factors, and we should try to honestly understand how big a role each one plays.
