Anti-revisionism
Anti-revisionism is the communist opposition to revisionist and opportunist tendencies within the working class movement and exposing deviations from Marxist principles. Opposition to revisionism represents a core aspect to the broader political struggle against capitalist ideology, as revisionism represents a counter-revolutionary movement which serves the interests of the bourgeoisie. Modern anti-revisionism is known fully as anti-revisionist Marxism–Leninism, as its adherents uphold the developments made by the leading theorists of Karl Marx, Frederick Engels, Vladimir Lenin, and Joseph Stalin.
