"The fanatical Communist refuses to believe any unfavorable report or evidence about Russia, nor will he be disillusioned by seeing with his own eyes the cruel misery inside the Soviet promised land. It is the true believer's ability to "shut his eyes and stop his ears" to facts that do not deserve to be either seen or heard which is the source of his unequaled fortitude and constancy. He cannot be frightened by danger, nor disheartened by obstacles, nor baffled by contradictions because he denies their existence."
