Why is anarchism hostile to Marxism?

Marxism is a teaching that affects philosophy, politics and economics. He comes out with a revolutionary struggle against the oppression and exploitation of people. The goal of Marxism is to build a socialist and, on its basis, a communist society. Anarchism is a whole system of views based on human freedom. Anarchism denies any compulsory control and power of a person over another person. Unlike Marxism, anarchism is against any suppression of some people by others. Anarchism opposes any state mechanisms of coercion of people. Instead of the revolutionary planting of communism, anarchists advocated voluntary association and the choice of citizens. For this reason, anarchists cannot share the beliefs of Marxists.
