You people are hilarious, with your "Liberty!" and "Freedom!".
Authoritarianism is but a means to an end. The ends will always justify the means. So long as Lenin brings this Republic to the cusp of Communism, who cares of the methods he uses to get there?
So long as Lenin works for the betterment of this Republic and Revolution I will support him. Why?
Because my loyalty lies with the salvation of humanity in Communism, not some lofty ideal of liberty and freedom.
There is one exceptionally large, glaring hole in your argument: authoritarianism is never a means to an end, but an end in itself. Even if the person implementing it, in this case Lenin, doesn't have any aspirations to permenant dictatorship, and even if he has the best of intentions (which I sincerely believe he does), this changes absolutely nothing. The revolution is built upon worker's liberation. To deny them that liberty is to plant the seeds of counter-revolution. Unless a new revolution emerges to violently halt the Republic from continuing down this path, then the revolution is forever lost. Sooner or later we shall see a new Napoleon assume the position of Lenin and abolish the last vestiges of democracy and socialism. Socialism by halves is impossible! Liberty and democracy are not options, they are requisites!
