In simple terms, racism is the belief that distinct human races exist and that one race is superior to another. This definition is generally agreed by the Oxford English Dictionary, Merriam-Webster Dictionary (USA) and the Macquarie Dictionary (Australia).
Racism is a product of the complex interaction in a given society of a race-based worldview with prejudice, stereotyping, and discrimination. Racism can be present in social actions, practices, or political systems (e.g., apartheid) that support the expression of prejudice or aversion in discriminatory practices.
