Anger is contagious. Yeah, it would be best for the people who are the most angry to calm the fuck down, but that’s not likely to happen unless they interact with others who make their emotion dissonant. Thus why the onus is, unfortunately, on those who aren’t angry to move the needle. That’s kinda how we got to this position in the first place, since the lowest energy state of the system is everyone either keeping silent or exploding at each other. It takes effort from basically everyone to get to a higher energy, more stable state.
