'''Racism''' is making a [[moral]] judgment about a person based on skin color or ethnic heritage. The hatred of another person because of the color of his or her skin is racist; some use the term ''racism'' for the perceived difference in origin, as a member of an [[Ethnic Group|ethnic group]] .
The doctrine of [[substantive due process]] in United States constitutional law can be used to invalidate racist laws. Alternately, the [[Equal Protection|equal protection]] clause of the [[Fourteenth Amendment]] can be used to do the same. ''See e.g.'' [[Brown v. Board of Education]], 347 U.S. 483 (1954).
