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. This concept has been used especially in the United States in debates over color-conscious policies (such as affirmative action) intended to remedy racial inequalities. Those who campaign for the interests of ethnic minorities commonly reject the concept of reverse racism. Scholars also 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 actively oppress them, and they are therefore not practicing "racism".
