sharply with black authors' descriptions of African Americans and their experiences in US society. African-American writers have sometimes been portrayed in African-American studies as retreating from racial issues when they write about "whiteness", while others identify this as an African-American literary tradition called "the literature of white estrangement", part of a multi-pronged effort to challenge and dismantle white supremacy in the US. Popular usage According to dictionaries, the word is commonly used to describe prejudice and discrimination based on race. Racism can also be said to describe a condition in society in which a dominant racial group benefits from the oppression of others, whether that group wants such benefits or not. Foucauldian scholar Ladelle McWhorter, in her 2009 book, Racism and Sexual Oppression in Anglo-America: A Genealogy, posits modern racism similarly, focusing on the notion of a dominant group, usually whites, vying for racial purity and progress, rather than an overt or obvious ideology focused on the oppression of nonwhites.

Furthermore, the meaning of the term racism is often conflated with the terms prejudice, bigotry, and discrimination. Racism is a complex concept that can involve each of those; but it cannot be equated with, nor is it synonymous, with these other terms. The term is often used in relation to what is seen as prejudice within a minority or subjugated group, as in the concept of reverse racism. "Reverse racism" is a concept often used to describe acts of discrimination or hostility against members of a dominant racial or ethnic group while favoring members of minority groups.

Scholars commonly define racism not only in terms of individual prejudice, but also in terms of a power structure that protects the interests of the dominant culture and actively discriminates against ethnic minorities. From this perspective, while members of ethnic minorities may be prejudiced against members of the dominant culture, they lack the political and economic power to
