Abstract: There are minority groups in every human society, which are often leftovers of the “one” major group of persons within such society viewed as the self-contained group that has nothing to do with the “other” minority groups. The Other is conventionally seen as a threat to the one. Othering within societies invariably results in the exclusion of the Other from the one. By Othering, we mentally or practically classify an individual or group as “not one of us” and, therefore, inferior or less a human person than we are, a process of casting another person, group, or object into a position or role different from mine or ours, and I or we consequently establish my or our identity in opposition to the Other person in a relationship of superiority that allows me or us vilify the Other. Through Othering, we create a system of social exclusion that systematically blocks the Othered minority individual or group from rights and opportunities that are fundamentally the prerogative of all. Hence, issues of justice for the Othered minority naturally arise. This is manifested in the xenophobic treatment of African foreigners in South Africa and Christian minority groups in the mainly Muslim North of Nigeria. The socially excluded is confined to the fringe of society as the minority, whose basic and fundamental rights become privileges by virtue of the Otherness. This chapter critically analyzes and evaluates the manner of othering and exclusion of minority groups in African societies. My primary concern is to examine the role of African communitarian theory in the face of Othering in African societies. I argue that our constant awareness and acknowledgment of our commonness beyond self-contained groups ensures justice and equity in our interpersonal relationships in any human society.
