Value-form
The Western Left academics are nowadays very happy to talk about "varieties of capitalism", but talking about "varieties of socialism" remains almost an absolute "no-no". Most Marxists continue to believe in "only one" (Marxian) socialism: either that, or nothing at all. "Either" a society or movement conforms to the true concept of socialism, "or" it does not; and if it does not, it "cannot be" socialism. However, precisely "because" there are many different Marxist beliefs about socialism, Marxists cannot agree among themselves whether Soviet-type societies were socialist, capitalist, or something else. Some countries meet with the moral expectations which Marxists have, and others do not.Originally Marx and Engels themselves had heckled the advocates of "true socialism", but later Friedrich Engels and Karl Kautsky promoted Marxist socialism as the one and true "scientific socialism" within the Socialist International. When he was 43 years old, Lenin stated: "The Marxist doctrine is omnipotent because it is true". Lenin's Communist International (a deliberate split with the social democrats) adopted Marxist socialism as its official political doctrine.
State atheism
A communist state, in popular usage, is a state with a form of government characterized by one-party rule or dominant-party rule of a communist party and a professed allegiance to a Leninist or Marxist–Leninist communist ideology as the guiding principle of the state. The founder and primary theorist of Marxism, the nineteenth-century German thinker Karl Marx, had an ambivalent attitude toward religion, viewing it primarily as "the opium of the people" that had been used by the ruling classes to give the working classes false hope for millennia, whilst at the same time recognizing it as a form of protest by the working classes against their poor economic conditions. In the Marxist–Leninist interpretation of Marxist theory, developed primarily by Russian revolutionary Vladimir Lenin, religion is seen as negative to human development, and communist states that follow a Marxist–Leninist variant are atheistic and explicitly antireligious.
