Being a "racist" once meant that the person believed that a race of people is inherently superior or inferior to other races, or that the person harbored hatred for a given race. My observation is that the number of persons who are "racist" using this traditional definition of the term has declined substantially.
I would like to propose a newer definition of the term. A "racist" is someone who is obsessed with race. A "racist" is someone who sees race in every situation. A "racist" is someone who always has a person's race at the forefront of their thoughts.
