Reply #83: Um? At least I realize that atheism is not an economic system.

[humblebum]

Communism: A theory that is based on a collective society in which all land and capital are socially owned and political power is exercised by the masses. 1) A theoretical economic system characterized by the collective ownership of property and by the organization of labor for the common advantage of all members. 2) Communism: a) A system of government in which the state plans and controls the economy and a single, often authoritarian party holds power, claiming to make progress toward a higher social order in which all goods are equally shared by the people. b) The Marxist-Leninist version of Communist doctrine that advocates the overthrow of capitalism by the revolution of the proletariat.

You are seriously confusing the two. Atheism was becoming quite established in tsarist Russia long before the Revolution. Not all atheists were communists.

If God really existed, it would be necessary to abolish him.
