To what extent do we live in a free country?  To what extent should we control the actions of individuals when those actions have no direct or significant affect on others except in their minds.  Those who would restrict smoking resort to the notion that second-hand smoke comprises a direct and significant threat to their bodies.  In many cases, this is nonsense, but the drive to control is legitimized by a direct and significant physical effect.  In the case of a person applying black make-up, the only adverse effect is admitted to stem from the minds of others.  Kinda like the Spanish Inquisition where people were burned at the stake for wrong thinking.  Racism only has meaning when it translates into action.  When folks throw around racism accusations without without actions of direct and significant consequence (based on intrinsic effect not interpreted effect), they only project their worldview.  It is important to distinguish the real from the presumed.
