I suspect this only seems reasonable if you've never experienced a healthy work environment. I probably would have agreed with you when I was in my twenties, working at a startup with another bunch of twenty-year-old guys and a CEO who was in over his head. It wasn't unusual for the whole company to yell at each other in a meeting room. The stakes seemed high then, but they seem ridiculous in hindsight, as does my own behavior.

Thirty years later, the stakes are much higher, and the temperate is much lower. This is precisely because we can't afford this behavior, and we can't afford to deal with people who can't control themselves and behave professionally in high-pressure situations.
