White supremacy or white supremacism is the racist belief that white people are superior to people of other races and therefore should be dominant over them. White supremacy has roots in scientific racism, and it often relies on pseudoscientific arguments. Like most similar movements such as neo-Nazism, white supremacists typically oppose members of other races as well as Jews.
The term is also typically used to describe a political ideology that perpetuates and maintains the social, political, historical, or institutional domination by white people (as evidenced by historical and contemporary sociopolitical structures such as the Atlantic slave trade, Jim Crow laws in the United States, the set of "White Australia" policies from the 1890s until the mid-1970s, and apartheid in South Africa). Different forms of white supremacism put forth different conceptions of who is considered white, and different groups of white supremacists identify various racial and cultural groups as their primary enemy.
In academic usage, particularly in usage which draws on critical race theory or intersectionality, the term "white supremacy" can also refer to a political or socioeconomic system, in which white people enjoy a structural advantage (privilege) over other ethnic groups, on both a collective and individual level.
In the USA in 1993 it was reported that increasing numbers of white supremacists are forsaking local action, such as cross burning, to build larger, mainstream constituencies, notably through satellite television. One such programme is broadcast over 65 local cable channels. White supremacist views include advocacy of the the death penalty for homosexuals, anti-semitism (quotations from the Protocols of the Elders of Zion), and opposition to racial integration as a sin. It is alleged to be a violent sub-culture and a vanguard political cause. Such groups tend to have sympathies with neo-Nazi and right-wing radical movements.
Deeply ingrained notions of white supremacy are the reflections of a world view which puts the most powerful capitalist countries at the global centre, declaring them "developed", while the countries of Africa, Asia and Latin America are peripheralised and deemed to be "underdeveloped". These notions have to be challenged.
