Aggression counts as authoritarian when authority sanctions it.

Evidence

For another contrast, high RWAs showed more hostility on the Posse and Trials measures than high SDOs did. Again, I think this reflects the different roots of aggression in the “submissive” and the “dominating.” In the Posse and Trials situations established authority sanctioned punishment, and that means a lot more to authoritarians than it does to social dominators. — John T. Jost and Jim Sidanius, Political Psychology, 996

By “aggression” I mean intentionally causing harm to someone. The harm can be physical injury, psychological suffering, financial loss, social isolation, or some other negative state that people usually try to avoid. Aggression is authoritarian when it is accompanied by the belief that proper authority approves it or that it will help preserve such authority. — Bob Altemeyer, The Authoritarian Specter, 145

• DEFINE: Operationalizes authoritarian aggression as harm mediated by perceived authority sanction — key to linking prejudice to authoritarianism.
