I think you're 100% right. This was something I previously noticed while working in the media sector, not with anger, but stress. Some people would seem to purposely stress themselves up about very minor incidents, and I think there was a subconscious craving for an adrenaline upper and dopamine downer guiding their actions. It's definitely a good general practice to talk down people who get themselves worked up, but I've met plenty who just won't allow that. I've also spent enough time of my life trying to get people to calm down, now I just want to exchange clever wit with strangers and appreciate silly things.
