Many women are not attracted to work in fields populated 90% by males. I believe this to be a more subtle problem that you suggest; you might eliminate all sexual harassment and it would still be the case.
What I am saying, is that the two biggest complaints that women who have worked in this industry have stated to me, are being hit on, and being harassed. Not as a single incident, but as a pattern. The only argument you could make against this is that I'm lying, and women haven't actually said these things to me.

First, that's lacking in civility, you've been here long enough to know that tone isn't appropriate.
Now then. The fact that your experience is not statistically significant isn't a possible counter argument? In order for you to be right, you would need evidence not only that most female mathematicians were harassed, but that they left the field because of if. If you have exit interview data for a random sample of former mathematicians, there are a lot of people here who would probably love to talk to you.
This is an especially unfortunate stance given that this is an article about math.
Edit: I make no claims one way or the other, I'm only talking about statistical validity.
Question: had they worked in the same company or same geographical area? I found that there is big difference between how companies and groups treat people.
Men in specific industries have a higher likelihood to sexually assault women, so much so that it pushes 90% of the women out of an industry with greater than 10M people. Do you understand how delusional that is?
