I m sorry man, but if you read the platform, the new type party (yeah, the leninist CP) comes to mind.
And why the fuck do its writers say that 'it is not centralist'!?
There is a general line - a basic thesis which is voted and ALL members must adhere to and support
There is centralism - the general anarchist union is responsible of the actions of every member, and every member is responsible and represents the general line that the GAU stands for.
Every 'cell' of the GAU (every organization that is a part of it) is ideologically guided and led by GAU.
So in my (poor,o be honest) opinion, the criticism has a basis.
