The unconditional hate of a certain race.
Unfortunately, the term is now grossly overused and no longer has meaning. Ignorant juveniles now believe that referring to a person by their race is racist in some way, like saying that a person is black is some kind of racial profiling. Ridiculous.
Ultimately these people just look like ignorant idiots who want to seem intelligent. They will bring race into a conversation at any given time, yet YOU are the racist somehow.
