Jesus. They are still people. You want to ostracize them from all society and prevent them from earning a living in their chosen career?
'Sexual harassment' is also a catch-all term that can encompass all kinds of actions. It could involve a clueless, inexperienced 20-something asking out his co-worker and misreading her signals - fuck that guy right? Throw him out of society and forget him forever, right?
And I have yet to see any evidence for this "toxic sexist" atmosphere that apparently is part of the Uber culture. This isn't it. 20 people were fired out of 12,000.
