Communism is not about a stateless, classless, society, nor is it about God.
It is precisely about a political upper ruling class; dictating everything belongs to the upper political state; and the upper ruling class (ruling the political state); dictates what, when and how much the entire "lower" class (entire public at large) can and can not have.
It is not about God; but rather about GREED and POWER of human men.
And yes it does exist; some claiming the Communist title; some claiming the title of Socialist.....A Communist being more of a strict adherent to Karl Marx teachings; and a Socialist more selective in following Karl Marx teaching; as embracing his teachings, that one who earns more should provide for the other who earns less; which is the same thing promoted by Socialists in the US, who want the higher earners to provide for them.
God Bless.
