far more women driven from phys sci by harassment than men by geekshaming

This seems to silently assume that women are not geekshamed.

Otherwise the proper comparison would be "more women driven from phys by harassment than both men and women by geekshaming", if we want to argue that geekshaming is not a problem. We should not automatically assume that focusing public attention on a scientist's shirt instead of their scientific results will have zero impact on geek women.

Edit: Not to mention that we didn't lose Matt Taylor. He still has the same job as a scientist with the ESA.

In other words, the original quote is, simply, a lie. Perhaps the "rationality" aspect is to remind people of all affiliations how readily people will lie for politics?
