Tail-ism... so a revolutionary party will look at a mass of workers and just assume that they will make the right decisions all on their own while the party is most just sitting back being a spectator.

IF, the mass of workers do something good, the revolutionary party committing a tail-ism might take credit for it.

IF, the mass of workers do something bad, then its all the fault of the workers and not the revolutionary party in any way.

In both situations, this revolutionary party hasn't taken the lead by actually doing any work educating, agitating, or organizing the workers.
