What are the forms of racial prejudice?

The manifestations of racial discrimination are openness, legality, concealment and practicality. In South Africa, racial discrimination is manifested in apartheid, which is the basic national policy of white racists and has a history of more than 300 years. Since the mid-20th century, white racist authorities have promulgated more than 100 racial discrimination laws. Blacks and Indians in America, aborigines in Oceania, former colonial immigrants in Europe, ethnic minorities and foreign workers, "tribesmen" and caste groups in Asia are all victims of today's racial discrimination.
