This statement voices the obvious from a geopolitikal prospective. The religion as practiced in Eaurope and the Russia pre 1917 was a state sponsored religion that with pagentry and drama allowed the little folk to let off steam. I am not taking anything away from a "true believer" but speaking from an organizational standpoint. Upheavals and wars were tempered by the messages from the pulpit which allowed acceptance of pain and suffering much like taking opium does. I dont think he spoke of it hatefully, just recognising a fact on the ground.
thanx,
