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 ideology or practice through demonstrated power of perceiving the superiority of one group over others by reason of race, color, ethnicity, or cultural heritage. In the United States and elsewhere, racism is manifested at the individual, group, and institutional levels.
