Communism is part of Western civilization. Western civilization created it.
It has become a way to justify imposing the old idea of total control of the population by an elite group.
Western Civilization originates from elite control of a national group.
Ever heard of Sparta? Rome? British, German, Austrian, Russian empires?
Elite control is practically the entire history of Western Civilization until the suicide of WW I allowed the silly ideas of Woodrow Wilson and Colonel House to wreck the world.
