Insofar as the proletariat is invested in the system, you must use that system.

This is just bowing to sponteneity. The party’s role is to raise the consciousness of the proletariat to their level, not to remain where the working classes are at. That’s the purpose of political parties, to organize and create proletarian intellectuals as a counter to bourgeois intellectuals. Otherwise the proletariat stays at the level of trade union consciousness if it has no means to see the political struggle as a whole.

Stop dragging Lenin through the mud to justify supporting imperialists.
