Anti-communism is called opposition to communism .Most anti-communists reject the concept of historical materialism, which is a central idea in Marxism. Anti-communists reject the Marxist belief that capitalism will be followed by socialism and communism, just as feudalism was followed by capitalism. Anti-communists question the validity of the Marxist claim that the socialist state will "wither away" when it becomes unnecessary in a true communist society.<?xml:namespace prefix = o />
Anti-communists argue that the repression in the early years of the Bolshevik regime, while not as extreme as that during Stalin's reign, was still severe by reasonable standards, citing examples such as Felix Dzerzhinsky's secret police, which eliminated numerous political opponents by extrajudicial executions, and the brutal crushing of the Kronstadt rebellion and Tambov rebellion. Some anti-communists refer to both Communism and fascism as totalitarianism, seeing similarity between the actions of communist and fascist governments. Historian Robert Conquest has argued that Communism was responsible for tens of millions of deaths during the 20th century.
Opponents argue that Communist parties that have come to power have tended to be rigidly intolerant of political opposition. These opponents claim that most Communist countries have shown no signs of advancing from Marx's socialist stage of economy to an ideal communist stage. Rather, Communist governments have been accused of creating a new ruling class (a Nomenklatura), with powers and privileges greater than those previously enjoyed by the upper classes in the pre-revolutionary regimes.
