"I am against the violation of civil rights by Hitler and Mussolini as much as you are, and well you know it. But I am also against the wholesale murders, confiscations and other outrages that have gone on in Russia. I think it is fair to say that you pseudo-communists are far from consistent here. You protest, and with justice, each time Hitler jails an opponent; but you forget that Stalin and company have jailed and murdered a thousand times as many. It seems to me, and indeed the evidence is plain, that compared to the Moscow brigands and assassins, Hitler is hardly more than a common Ku Kluxer and Mussolini almost a philanthropist."
