Well the article itself says this but it's still worth saying in reply to the headline - of course a lot of women in tech won't be reacting to bad behavior. First, they have real job to do. Second, the person who gets fazed by this kind of behavior is showing weakness, looks shrill and like an outsider and so-forth. Third, these are the women in the industry who are used this kind of bad behavior. If they were fazed, they would have left and indeed arguably many do.
Anyway, is it women's job to fight bad, sexist behavior or is it everyone's job? I vote everyone.
