I was about to post this on halfchan, but then I realized it might be too in depth for them.
So there are way too many parallels between the French Revolution and the Russian revolution to ignore, plus all the Orwellian shit like the Committee of Public Safety being responsible for the terror.
Also you have a moderate faction slain by the radical faction in both historical periods. Both the Bolsheviks and the Montangnards slaughtered the Mensheviks and Girondins respectively. Both instituted a terror, murdered Christians and spun elaborate lies about the Christian religion. Both had master propagandists who died brutally in the form of Jean-Paul Marat and Leon Trotsky, and both periods of terror were overseen by "incorruptible" tyrants Maximilien de Robespierre and Vladimir V. Lenin.
But arguably these men considered themselves rationalists, following in the footsteps, and living out the dreams of men like Voltaire, Rousseau, Hegel and Karl Marx. Why the hell is the modern left so irrational? Debating the limits of rationality used to be the refuge of counter-revolutionary men like le Comte de Maistre. What makes people revolutionaries if from such a rationalistic pedigree, modern radicals are totally irrational and completely reject anything beyond "lived experience?" Is bloodlust the motivator and rationality anterior?
How depraved are people? Could it be that they really hate so genuinely, and in such vast numbers?
