Moral exclusion
Moral exclusion is a psychological process where members of a group view their own group and its norms as superior to others, belittling, marginalizing, excluding, even dehumanizing targeted groups. A distinction should be drawn between active exclusion and omission. The former requires intent and is a form of injustice, known as moral exclusion; while the latter is thoughtlessness. The targeted group is viewed as undeserving of morally mandated rights and protections. When conflict between groups escalates, the in-group/out-group bias between the groups heightens. Severe violence between groups can be either the antecedent or the outcome of moral exclusion. At its extreme it is a bidirectional phenomenon that defies precise origin.
