As regards this "organic centralism" definition, I think we have to be honest and admit that 'organic' can only justly define a relationship lacking a chain of command. As in perhaps the free association of all people that characterizes not socialist society but a communist world. But until such time as we have that kind of order, democracy is, I think, a more correct term by which to define revolutionary political structures, even as we seek to get beyond that narrow horizon; the horizon of things like 'democratic rights', etc. If anything, I was kind of more suggesting in the OP that communist parties should be less, not more, heavily centralized than they have been since before the October Revolution; that we need a party of a new type. And I was seeking to fish out some examples of alternatives of that nature leftist communists might have to offer, to my as yet dismay.
