>Racism isn't about race. Otherwise it wouldn't exist: there is only one human race. Offtopic but I wonder, where does this notion come from? Biologically there is more variance in the humans species than in others species that we consider to having races. One example of big phisical distinction is themarathon winner's race, most modern marathon winners descend from the same tribes, and have very distinct physiology due to millenia of adapting to persistence hunting. Literally evolution. My definition of racism was always: race based discrimination. Aa in I should not treat you different because of your race. The definition about denying even the existence of different human races seems weird to me, as there seem to be a lack evidence to support the inexistence of different human races.
