I don't think we need to create perfect communists.

What we need to create is a party large enough and organised enough to seize the moment. And a proletariat angry enough to do revolution.

ANY party that is large and well organised enough to.... ORGANISE... Will defacto become the vessel of revolution because people will be forced into supporting whatever is realistic and available when it happens.

Hamas for example has all the weapons, largely because of supporting allies in Hezbollah and Iran. This used to be the PFLP but then the soviet union fell and that's where their supplies were from so they've dropped off as the most realistic vessel for resistance in Palestine, people support the most realistic thing that can do resistance and that thing happens to be who has the most weapons.

The same scenario plays out in revolutions around the world. Those with the most organisational power (and the most ability to do violence) will leap to the forefront of a revolutionary situation. The people will want neither of the main parties, they will want whatever the most realistic next possible is. The job of communists is to become that and be ready for the opportunity, then seize it decisively when it comes and fend off opposition.

The members of the party need to be perfect communists, for obvious reasons, the party needs to be led well and have good ideology. The people that follow it do not, it's beneficial but not important for purism among the proletariat itself.
