"Time and again the focus of the terror was less on targeted individuals than on groups of people. The purpose of terror was to exterminate a group that had been designated as the enemy. Even though it might be only a small fraction of society, it had to be stamped out to satisfy this genocidal impulse. Thus, the techniques of segregation and exclusion employed in a "class-based totalitarianism" closely resemble the techniques of "race-based totalitarianism." The future Nazi society was to be built upon a "pure race," and the future Communist society was to be built upon a proletarian people purified of the dregs of the bourgeoisie. The restructuring of these two societies was envisioned in the same way, even if the crackdowns were different."
