What do you mean by top-down utopian adventurism? The Russian Revolution? This is such a distortion of historical reality that I must recommend that you read a little about the events before coming up with such a distortion. Really, Rob, you have the most perverse determination to distort what Lenin stood for. In reality, Lenin was trying nothing else except to create a Social Democratic party in Russia, where none existed. There was nothing "utopian" about this. His party was not "top-down" either. Historians agree that the Mensheviks were far more "top-down" than the Bolsheviks. When the Russian people overthrew the Czar, they had expectations that the Kerensky regime would pull Russia out of the imperialist war and distribute land to the farmers. When he refused to do this, Socialists had no other choice except to fight for the goals of the February Revolution. The November Revolution was nothing more than the expression of the Russian people to secure the benefits they deserved when the Czar was overthrown.
