“Ethnicity” is an anti-concept, used as a disguise for the word “racism” — and it has no clearly definable meaning. . . . The term “ethnicity” stresses the traditional, rather than the physiological characteristics of a group, such as language — but physiology, i.e., race, is involved . . . . So the advocacy of “ethnicity,” means racism plus tradition — i.e., racism plus conformity — i.e., racism plus staleness.
