Mitt gets booed at the NAACP convention.

especially so as to distinguish it as inferior or superior to another race or races

racial differences produce an inherent superiority or inferiority of a particular racial group

It goes both ways. Believing one race is superior is just as racist as believing another is inferior. Doesn't matter which race is doing the believing.
