Engels defined Communism as” the doctrine of the conditions of the liberation of the proletariat” in the Principles of Communism. Building up on that, Communism is the end stage of Socialism, in which the state and money are abolished and all private property is commonly owned by the people. Socialism, and by extension, Communism are key in the liberation of the workers and toilers from exploitation and wage slavery. A socialist society is one liberated from the chains of poverty, discrimination, homelessness, bigotry and the ailments that plague capitalist societies. As such, Communism and Socialism can and should be accepted in order to further the liberation of the vast majority of the people.
That is why Communism must be accepted.
