The celebrated phrase, 'so much the worse for the facts', would satisfy only the high priests of Marxism, for Marxism also has its high priests, and these priests, like all others, daily deny the principles they claim to defend. Bolshevism is a living proof of this.
The hopes which inspire communism are, in the main, as admirable as those instilled by the Sermon on the Mount, but they are held as fanatically and are as likely to do as much harm.
Bertrand Russell, The Practice and Theory of Bolshevism (1920), Part I, The Present Condition of Russia, Ch. 1: What Is Hoped From Bolshevism.
The Bolshevik policy of terror was more systematic, better organized, and targeted at whole social classes. Moreover, it had been thought out and put into practice before the outbreak of the civil war. The White Terror was never systematized in such a fashion. It was almost invariably the work of detachments that were out of control, and taking measures not officially authorized by the military command that was attempting, without much success, to act as a government. If one discounts the pogroms, which Denikin himself condemned, the White Terror most often was a series of reprisals by the police acting as a sort of military counterespionage force. The Cheka and the Troops for the Internal Defense of the Republic were a structured and powerful instrument of repression of a completely different order, which had support at the highest level from the Bolshevik regime.
