@dirge must have unhappily found himself in double-bind. If the distinction between "legitimate" racialism and "illegitimate" racialism is based on racialism, then that is racialist. So either he admit that some kinds of racialism are right and permissible or concur that his definition is racialist which would then logically entail he condones certain kinds of racialism.

This word hijacking is so common. It is often the case that identitarian opponents of this falsified definition of racialism will take an equally absurd stance, accepting the premise that there is only one race, the "human race," by saying, "There is no such thing as racism" or "Only bigots think the 'races' are different."

There are races. Scientists recognize greater differences in the physiological quality of human beings between races than between individuals within a race. The pseudo-scientific idea of racialism has got into people's heads, but in-group - out-group prejudice based on differences in appearance, language, customs, etc., has existed since our animal ancestry.
