If everyone was atheist

[Napoléon]

This is interesting. Where can I find out more about this? I never knew the CCCP had such a restriction.

I read about it here:

The USSR needed the support of the Middle East in its larger battle against Western capitalism, and feared alienating Muslim nations by being too heavy-handed in its treatment of its own Muslim population in southern Russia. As a result, although the practice of Islam was controlled, Muslims could become members of the Communist Party while their Orthodox counterparts could not.

But I know Islam was treated a lot differently than Christianity by the Russians:

In regard to Communism being 'fucked-up' I would say Capitalism is equally as 'fucked up' because in the West people live off of the Third World. They have to in order to maintain their standard of living. The Capitalist economy would collapse if didn't have a huge supply of cheap labour. The poor suffer just as much, if not more, because of Capitalism.

I don't disagree but I don't see what this has to do with OP's question and how atheism plays into it.

Communism itself isn't inherently a bad political system. Secularism can be, and in my opinion, really is a great thing. What you saw in Marxist-Leninist Russia was the most twisted version of these two things, but in the discussion about religion vs atheism, one of these plays a direct part in politics, the other just plain can't because of what it is. I'll let you decide which is which.
