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).
To some, racism denotes a set of hereditarian judgments about educability or criminality. To others, it implies virtually any kind of animus or stereotype based on ethnic origin. This is a classic problem of semantics: words get in the way of settling differences.
