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 refers to various beliefs maintaining that the essential value of an individual can be determined according to a perceived or ascribed racial category and that social discrimination by race is therefore justifiable.
