To defeat the passive-aggressive warrior, you must first work on yourself. This means being acutely aware of the blame-shifting tactic as it happens. Squash any feelings of guilt it might begin to make you feel. These types can be very ingratiating, using flattery to draw you into their web, preying on your insecurities. It is often your own weakness that sucks you into the passive-aggressive dynamic. Be alert to this.
