Racism

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. People with racist beliefs may resent certain groups of people according to their race. Racial discrimination typically points out taxonomic differences between different groups of people, even though anybody can be racialised, independently of their somatic differences. According to the United Nations conventions, there is no distinction between the term racial discrimination and ethnic discrimination.
Some sociologists have defined racism as a system of group privilege. In Portraits of White Racism David Wellman (1993) has defined racism as "culturally sanctioned beliefs, which, regardless of intentions involved, defend the advantages whites have because of the subordinated position of racial minorities". Sociologists Noël A. Cazenave and Darlene Alvarez Maddern define racism as “...a highly organized system of 'race'-based group privilege that operates at every level of society and is held together by a sophisticated ideology of color/'race' supremacy. Racist systems include, but cannot be reduced to, racial bigotry,”.
So if a certain person, for eg: white person, doesn't like a black person just because of his color, or any other genetical difference, it's considered racism.
