Racism usually involves the idea that one's own race is superior and has the right to dominate others or that a particular racial group is inferior to the others.
Discrimination furthermore is an action that denies social involvement or human rights to categories of people based on prejudice. This includes treating an individual or group based on their actual or supposed membership in a certain group or social category. Discrimination does not have to be based on race at all but could be for any reason. Such reasons could include; wealth, class, religion, political categories, or even things as irrational as hair color, weight, complexion, or even
height.
