...Class struggle will affect even Marxist theory where the ruling ideas of the ruling class will be unconsciously ( and sometimes consciously) adopt… - J. Moufawad-Paul

Revisionism is an immanent danger for the revolutionary movement; anti-revisionism is an immanent struggle within this movement so as to constantly redefine the movement’s basis. What is meant by “revision” here is a revision of the basis of Marxist theory, that which makes Marxism properly Marxism: the theory of class struggle. When Marxist theory is altered so as to argue that class struggle is no longer necessary, that class revolution is not the motive force of history and that social change can be brought about by a peaceful co-existence between classes (through rational debates, legal reform movements, etc.) then we find ourselves in a theoretical terrain that is no longer Marxist because it is a terrain that already exists, the terrain of liberalism. We will return to the meaning of “revisionist” itself in a later section; what matters at this point is to understand that an opportunistic rejection of the Marxist theory of class struggle that brands itself with the name “Marxist” is always a possibility with each and every creative adaptation of Marxist theory to particular contexts.

Revisionists believe that the cardinal sin of communism is not opportunism but "infantile ultra-leftism" and, basing themselves on a selective reading of Lenin's analysis of ultra-leftism, will argue that any criticism of revisionist practice (any open demand for a revolutionary politics that produces militant practice) is the very ultra-leftism that threatens the left.

We need to recognize that Maoism as a concept stands over and above the name of Mao Zedong, just as Marxism and Leninism must stand over the name of Karl Marx and Vladimir Lenin, respectively.
