oh no, fragile men are scared they might make women uncomfortable?
Oh, stop being an asshole.
The issue has nothing to do with “fragility”, and you know it doesn’t. The issue is the current standard that corporate HR departments manage to, in part dictated by vague regulations from the EEOC, is that you can lose your job by “making women uncomfortable.”
Since what makes a person “uncomfortable” in this regard is wholly subjective and individual, the man has no idea (beyond the obvious) what sort of verbal banter will or will not make a particular co worker “uncomfortable”; all he knows is he can lose his job for it.
So, faced with THAT, human nature dictates that he opt for the most careful behavior around female co-workers possible. And what the original article points out (not particularly well in its examples or argumentation, but the POINT is valid) that this “careful behavior” may not serve women particularly well as far as their desire for career advancement is concerned.
