definition of racism - wikipedia

link

Racism is generally defined as actions, practices, attitudes, or beliefs that reflect or support the racial worldview: the ideology that humans are divided into separate and exclusive biological entities called "races".

Some definitions of racism also include discriminatory behaviors and beliefs based on cultural, national, ethnic, caste, or religious stereotypes.

Racism and racial discrimination are often used to describe discrimination on an ethnic or cultural basis, independent of whether these differences are described as racial. According to the United Nations convention, there is no distinction between the terms racial discrimination and ethnic discrimination, and superiority based on racial differentiation is scientifically false, morally condemnable, socially unjust and dangerous, and that there is no justification for racial discrimination, in theory or in practice, anywhere.
