If you were imprisoned in their concentration camps or being tortured by their secret police, you didn’t care whether they said they were “National Socialists” or “genuine Marxist “internationalist” socialists.” George Orwell was once a true Marxist believer like yourself but he eventually realised that Marxism is just rhetoric to convince young fools to fight to establish the Party’s dictatorship. As he put it in 1984:
“ The Party seeks power entirely for its own sake. We are not interested in the good of others; we are interested solely in power, pure power. We are different from the oligarchies of the past in that we know what we are doing. All the others, even those who resembled ourselves, were cowards and hypocrites. The German Nazis and the Russian Communists came very close to us in their methods, but they never had the courage to recognise their own motives. They pretended, perhaps they even believed, that they had seized power unwillingly and for a limited time, and that just around the corner there lay a paradise where human beings would be free and equal. We are not like that. We know that no one ever seizes power with the intention of relinquishing it. Power is not a means; it is an end. One does not establish a dictatorship in order to safeguard a revolution; one makes the revolution in order to establish the dictatorship. The object of persecution is persecution. The object of torture is torture. The object of power is power.”
Never trust anyone who quotes Karl Marx: they cannot be trusted because they believe in things which have been proven over and over to be impossible: it is impossible to convince people of the truth when they are mired in doublethink and Marxist propaganda.
