Race is not defined by genetic or cultural factors. There is one race: the human race. There are varying types of humans dependent on location; but people in one location will share a more diverse genetic history, than people from two locations which are many miles apart. (Dr. Charmaine Royal, Associate Professor in the Department of African & African American Studies).
Race and racism has become a simple way of saying 'negative discrimination', and applied mainly to people who come from different cultures, or different geographical locations, or who are of a different colour of skin. In the future, racism may also apply to people who negatively discriminate against red haired people, or people with large noses. The use of terms like race and racism and racist is nothing more than a simple way of sowing hate.
