ROFL ... ask the still existing fans of Stalin if he was a communist or not! What Answer will you get, eh? Sorry ... but this splitting hairs, as we call it in my country, is just ridiculous and superfluous. Do all of these variants that I gave as an example refer to the works of Marx and Engels? Yes they do and even you cannot deny that fact! So they all have the same core - dot and exclamation mark! If they do refer by right or not is a point of endless discussion and at least a point of personal view and rating! And the fact is also that the works of Marx and Engels are pure theory and can never be applied practically ... simply because they are against the basic instincts of mankind! And it is an undeniable fact that all attempts at practical implementation have failed, or ended in pure dictatorship, oppression and countless millions of deaths ... until today! And even in this book of fairy tales by Marx and Engels there is talk of the "dictatorship of the proletariat", isn't it?
