My definition of a racist is this: An ignorant human being that believes the White 'race' is superior to all others. Heil Hitler! To continue the use of the word without any scientific proof of 'races' is to perpetuate the big lie.

LOL

So you agree that people of the white "race" can be racists. If you didn't, you wouldn't call them "racists" but instead, you would call them "white supremacists". Since you agree that the term "racist" can be used in the absence of any category called "race", you therefore are being inconsistant if you say it cannot be applied to any other groups of people.
