See the 10 Principles of the Communist Manifesto. Communism described in the Websters Dictionary is:
1 a: a theory advocating elimination of private property b: a system in which goods are owned in common and are available to all as needed.
2 a: a doctrine based on revolutionary Marxian socialism and Marxism-Leninism that was the official ideology of the Union of Soviet Socialist Republics b: a totalitarian system of government in which a single authoritarian party controls state-owned means of production c: a final stage of society in Marxist theory in which the state has withered away and economic goods are distributed equitably d: communist systems collectively.
Indoctrinate the children, and over a long period, Communism will be accepted. It’s up to you to learn what your school teaches because schools will fill their skulls with crap.
