This isn't a case where it was the first accusation nor was it where he or other people in management were unaware (the issue was escalated), the behavior was inappropriate.
The problem is the management was told there was an issue, repeatedly, with evidence, by several people, and choose to not act upon it. Doesn't matter if it's sexual harassment or incompetence, employees won't tolerate bad cultures if they can help it.
This is a lot of things, sexual harassment, work culture, accountability, office politics, etc., but some guy being clueless about women isn't one of them.
Also, "I know that sounds sexist" is a fucking terrible caveat.
I wonder if such things are limited to Uber or more widespread than we believe it to be. I have a fear that these incidents are more common than I believe them to be and that because we have our heads down and focusing on an end-goal, we don't notice that some of our colleagues are being traumatized by people we admire/put in positions of power.
I would agree with you that certain industries and areas would have equivalent if not higher prevalence. Investment banking comes to mind.
This is really sexist.
I think the technical term for this is "Some Grade A Bullshit", but it's been a while since I read a sociology textbook.
None of this really has anything to do with the case at hand though.
I would define sexism to be believing facts solely based on a persons gender. This does not mean that if you had evidence that one sex was better at something, and you reached a conclusion based on that, then that would be sexist.
For example, it's quite obvious that men are taller and stronger than women. It's not sexist to say that, as it's based on clear evidence.
I'm unaware of the evidence the original poster has, but I would leave room for doubt that he/she does have some before immediately branding him/her a sexist.
Besides which, if you understood my point I don't see how you could view a statement like "Gender X is better at Y" as being sexist in it of itself. You would need to see the supporting evidence or lack thereof of to decide whether the idea conveyed is sexist.
