Supremacism is the belief that a particular race, religion, gender, belief system or culture is superior to others and entitles those who identify with it to dominate, control or rule those who do not. Examples include supremacism based on ethnic or anthropological origins (white supremacy, black supremacy, ethnocentrism), sexuality (male supremacy, female supremacy) and religion (see below).
Supremacism, however, goes much further. A supremacist not only holds that any evidence and reasoning for his or her beliefs is superior to any other, but that those holding such beliefs have rights over those who do not. For example:
"American leadership is good both for America and for the world" - New American Century Project
Following the American Civil War, southern whites and former Confederates formed the secret society known as the Ku Klux Klan. They preached Anglo Protestant supremacy over all other races, as well as over Jews and Catholics.
Japan's military leaders during World War II repeatedly told the Japanese population that they were a superior race, destined to rule Asia and the Pacific.
Certain sectors of Jamaican-born religion of Rastafarianism preaches the supremacy of the black race and the need for Exodus back to Africa (Ethiopia).
Racial supremacy differs from racism in that, racism is the dislike or disrespect for a particular ethnic group. Racial Supremacy is the belief that one's own race is superior, dominant, chosen, smarter, more civilized, or more productive than any other race.
