"We define racism, also referred to as white supremacy, as the pervasive, deep-rooted, and longstanding exploitation, control and violence directed at People of Color, Native Americans, and Immigrants of Color that produce the benefits and entitlements that accrue to white people, particularly to a white male dominated ruling class" ("Racism 101," Showing Up for Racial Justice).
"Racism is different from racial prejudice, hatred, or discrimination. Racism involves one group having the power to carry out systematic discrimination through the institutional policies and practices of the society and by shaping the cultural beliefs and values that support those racist policies and practices" ("Racism Defined," Dismantling Racism Works Workbook).
Each source also provides more information, including the levels at which racism operates (e.g., cultural, institutional, and personal).
"White supremacy is a system of structural and societal racism which privileges white people over everyone else, regardless of the presence or absence of racial hatred. White racial advantages occur at both a collective and an individual level. We just updated this chart, which presents *some* of the ways people practice and reinforce white supremacy that they may not be aware of, or even think of as 'white supremacy.' If you are unsure of what any of these terms mean, please feel free to look them up. There is an abundance of scholarship and research on each of these things" (@theconsciouskid).
