Oddly enough, one of the best teams I was ever on was a group where people didn't collectively have steel rods up their asses. It ran well and efficiently. Teamwork was excellent. The boss was demanding but did a very good job at cultivating talent being much more effective at genuine "social justice" than most people that like to whine about it loudly.
It actually worked better than a climate of terror inspired by threats of litigation.
Despite the apparent "evil locker room atmosphere", people didn't push individual tolerances too much. Any real nonsense would have been dealt with most severely. If there was a problem you dealt with it then and there.
This Uber situation is basic leadership fail rather than a lack of political correctness or decorum.
