Racism from WikiPedia:

Racism is the belief that race is the primary determinant of human traits and capacities and that racial differences produce an inherent superiority of a particular race. In the case of institutional racism, certain racial groups may be denied rights or benefits, or get preferential treatment. Racial discrimination typically points out taxonomic differences between different groups of people, although anyone may be discriminated against on an ethnic or cultural basis, independently of their somatic differences. According to the United Nations conventions, there is no distinction between the term racial discrimination and ethnic discrimination.

Although the term racism usually denotes race-based prejudice, violence, discrimination, or oppression, the term can also have varying and hotly contested definitions.
