But aggression is not unintentional or accidental. If you bump into someone by accident and never meant them any harm, it is not an act of aggression, although the other person may misperceive it as one. Unfortunately, when Sue included “unintentional” slights, and when he defined the slights entirely in terms of the listener’s interpretation, he encouraged people to make such misperceptions. He encouraged them to engage in emotional reasoning—to start with their feelings and then justify those feelings by drawing the conclusion that someone has committed an act of aggression against them.
