Here is a list of terms that I will use throughout the discussion.  I will add other terms to the glossary as necessary.  This post will have a permalink in a sidebar on this site. 

Racism

Racism has many different definitions. Historically, it has been defined as the belief that race is the primary determinant of human capacities, that a certain race is inherently superior or inferior to others, and/or that individuals should be treated differently according to their racial designation. Sometimes racism means beliefs, practices, and institutions that discriminate against people based on their perceived or ascribed race. There is a growing, but somewhat controversial, opinion that racism is a system of oppression -- a nexus of racist beliefs, whether explicit, tacit or unconscious; practices; organizations and institutions that combine to discriminate against and marginalize a class of people who share a common racial designation, based on that designation.

Hegemony

Hegemony is the dominance of one group over other groups, with or without the threat of force, to the extent that, for instance, the dominant party can dictate the terms of trade to its advantage; or more broadly, that cultural perspectives become skewed to favor the dominant group.

Ethnocentrism

Ethnocentrism (Greek ethnos ("nation" + -centrism) is the tendency to look at the world primarily from the perspective of one's own culture. Many claim that ethnocentrism occurs in every society; ironically, ethnocentrism may be something that all cultures have in common.

Eurocentrism is the practice, conscious or otherwise, of placing emphasis on European (and, generally, Western) concerns, culture and values at the expense of those of other cultures. It is an instance of ethnocentrism, perhaps especially relevant because of its alignment with current and past real power structures in the world.

Marginalization

Marginalisation or marginalization (US) refers in general to the overt or subvert acts and trends within societies whereby those perceived as lacking function or desirable traits are killed or otherwise excluded from existing systems of protectionism, thereby limiting their means for survival.

Anti-racism

Anti-racism, like other general social attitudes, ideas and movements, has many variations and faces. At its simplest and least ideological, it consists simply in opposition to racism and racialism based on a sense that all races are basically the same, and we should all accept each other's differences. In more developed and ideological forms it tends to involve the belief that racism is both pernicious and socially pervasive, so that strong measures are called for to control and even eradicate it.
