The lack of women in numbers who play chess compared to males is simply the fact that both genders brains are wired different, men on average are simply better at pattern recognition which is crucial for chess.
I don't think that is the entire answer. At my job women outnumber men three to one, and the women come from many different countries and are all varying ages. I went around and asked "Do you play chess?" Four of the five scientists are women and none play chess. There are two mathematicians both are women who do not play chess. A strong majority of technicians at work are women and not one plays chess. A quick glance at new members who join everyday here on chess.com are male (minus the women who give the impression of being male to avoid online harassment).
Pattern recognition difficulties can't be the only issue if women in general have never touch the chess board. Cultural perhaps? Probably not since my job has enough different culture to make us a miniature version of the UN. Traditional perhaps? This I lean towards as chess has been seen as a "manly" game passed from father to son (as my father did to me but not my sisters).
So, the question I have is this: how can we get more women into the game of chess and create new traditions?

Obviously the leg and feet guy had a huge advantage, and it took me about 20 years to figure out how I would have handled that.

I'm glad we're spending our time so wisely
