Is democratic centralism inherently authoritarian?

Trotsky, Lenin and Kamenev (1919)

The inner regime of the Bolshevik party was characterized by the method of democratic centralism. The combination of these two concepts, democracy and centralism, is not in the least contradictory. The party took watchful care not only that its boundaries should always be strictly defined, but also that all those who entered these boundaries should enjoy the actual right to define the direction of the party policy. Freedom of criticism and intellectual struggle was an irrevocable content of the party democracy. The present doctrine that Bolshevism does not tolerate factions is a myth of epoch decline. In reality the history of Bolshevism is a history of the struggle of factions. And, indeed, how could a genuinely revolutionary organization, setting itself the task of overthrowing the world and uniting under its banner the most audacious iconoclasts, fighters and insurgents, live and develop without intellectual conflicts, without groupings and temporary factional formations? The farsightedness of the Bolshevik leadership often made it possible to soften conflicts and shorten the duration of factional struggle, but no more than that. The Central Committee relied upon this seething democratic support. From this it derived the audacity to make decisions and give orders. The obvious correctness of the leadership at all critical stages gave it that high authority which is the priceless moral capital of centralism. [*]
