A Cultural Revolution is a movement designed to preserve the political and financial power of a ruling elite by social rather than political or financial means. Thus the primary tools of a Cultural Revolution are not redistributing power via elections (politics) or financial reforms; the primary tools are public shaming and denouncements, purges of those in positions of authority, show trials, guilt-by-association, wholesale denouncements of entire classes and widespread accusations of anti-progressive ("counter-revolutionary") tendencies in which guilt is defined by all-or-nothing litmus tests of one's loyalties to the Cultural Revolution's strict ideology.

You haven't memorized Mao's Little Red Book? Off to re-education camp you go. Or house arrest, banishment, beatings, imprisonment or if the mob's blood lust demands it, execution.

The key dynamic of a Cultural Revolution is the oppressors appropriate the language of liberation as their favored tool of suppressing dissent, denouncing opponents and fueling widespread purges of anyone who might harbor the slightest potential to question the social suppression of dissent.
