Did Lenin and Mao Forsake Marx?

The author disagrees with some of the criticisms of his essay "What Is Maoism?" by Paresh Chattopadhyay related to ways of interpreting the Marxist classics and particular interpretations of Marx and Engels. He then deals with PC's pronouncements that Lenin misinterpreted Marx on socialism and was responsible for the degeneration of the Russian Revolution. He also deals with PC's theses that Mao was an ideological Stalinist, and that Cultural Revolution is alien to Marx's thought.
