If you dig deeper behind most acts of aggression you usually find fear.
Fear of not being enough.
Fear of not being considered part of the group.
Fear of not feeling important.
Fear of being overlooked.
Fear of being overtaken by a competitor.
Fear of losing standing.
Fear of experiencing physical/emotional pain.
One way to resolve acts of aggression within a community is to remove the symptom (the act or the person).
The problem is this increases the antagonist’s level of aggression towards you. Do this often enough and eventually one of them will have the skills and motivation to be as disruptive as possible.
Another approach is to consider if you can resolve the underlying fear. It’s not always an option, but when it is, try it.
