Factions are a sign of illness in a party.

Revolution is an instrument, like a party is an instrument.

There are no factions in the Liberal Party.

Furthermore, there is absolutely no contradiction between the separate organizations of revolutionary vanguard militants and their participation in the mass organizations of the working class.

Workers do not strike every day, they cannot do that the way they function in the capitalist economy. The way they have to live by selling their labor power makes that impossible.

And you cannot have a socialist revolution commandeered from the top, ordered around by some omniscient leader or group of leaders.
