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 the belief that different inherent traits in racial groups justify discrimination. In the modern English language, the term racism is used predominantly as a pejorative epithet. It is applied especially to the practice or advocacy of racial discrimination of a pernicious nature, which is often justified by recourse to racial stereotyping or pseudo-science.
