To rephrase Stalin, there is the dogmatic way to do Marxism, and there is the pragmatic way. We follow the pragmatic way. I think we ought to entertain a network where everyone is welcome as long as they are friendly to the Marxist-Leninist cause and do not seek any trouble.
That being said, religion is often manipulated and corrupted when intermingling with political economy by organising itself into churches, sects, cults, and affiliated marketing schemes. Depending on their historic tendency to exert pressure against the economic welfare of the proletariat, to intrude upon the orderly proceeding of science and statecraft, to involve themselves in offences against the common good and the dealings of the criminal underworld, and to peddle anti-communist hysteria, the role of predatory religious organisations is to be shunned, and in particular clearly distanced from the genuinely progressive, proletarian aspect of the faith.
