Discrimination is an assault on the very notion of human rights. Discrimination is the systematic denial of certain peoples' or groups' full human rights because of who they are or what they believe. It is all too easy to deny a person's human rights if you consider them as "less than human". http://www.amnesty.org/en/discrimination
American Association of Colleges and University Definitions:
Diversity: Individual differences (e.g., personality, learning styles, and life experiences) and group/social differences (e.g., race/ethnicity, class, gender, sexual orientation, country of origin, and ability as well as cultural, political, religious, and other affiliations).
Inclusion: The active, intentional, and ongoing engagement with diversity--in the curriculum, in the co-curriculum, and in communities (intellectual, social, cultural, geographical) with which individuals might connect--in ways that increase awareness, content knowledge, cognitive sophistication, and empathic understanding of the complex ways individuals interact within systems and institutions.
Equity: The creation of opportunities for historically underrepresented populations to have equal access to and participate in educational programs that are capable of closing the achievement gaps in student success and completion
Whiteness includes several factors, historical and legal practices in the United States, systems of social beliefs, and norms all of which impact how we think about issues of race. The ideas of race are perpetuated by the social structure.
White individuals in the United States have access to different opportunities than do people of color. The advantages are often not recognized by the group in power, it has never occurred to them, which once again is a privilege of being white. There are several examples of white privilege in current U.S. society: curriculum reflects the dominant group experience, not American Indian experience, the African American experience, nor other minority groups, dominant group members expect to see themselves represented in politics, the media, and business. Dominant group members don't ever question whether some instance happened because of their race or ethnicity.
