If you actually knew anything about Marxism instead of just parroting what your talking heads told you you would know they were pretty down on any religion, and that the Soviets had far more trouble with Islamic extremists than we ever have.
Actually Creepazoid, the Soviets had very little trouble with the Muzzie beasts. The Chechen Beslan attack was 2004, more than a decade after the fall of the USSR. You are ignorant and uneducated. Lenin initially embraced many religious leaders, particularly Catholics, who had a lot of support for the Bolshevik movement. Russian Orthodox was the official religion of Tsarist Russia, which angered Rome.
