Have the Chinese really passed that point, already?
Yes and no. A lot of it comes down to just how much of a patchwork the Chinese economy actually is, so while the Stalinist project played out as Bordiga described in some regions, in others the peasantry are still economically constituted more or less as they were before the civil war. I don't think that any Unified Theory of Stalinism can encapsulate the complications of Chinese economic development, Bordiga's merely offers a useful insight.
You also say in post 143 that "if anybody needs more explanation in detail, I´ll be happy to oblige". So oblige.
Indeed: a broken arm is a property, a rationalist epistemology is a property, a reputation for boorishnness is a property.
Ah, so you're just using the word to denote something entirely different than what everyone else uses it to denote. Glad we cleared that up.
"Communism is its true sense has never been practiced", well, almost nothing in it's purest form can. Take Democracy for example. You don't want a pure Democracy do you, just parts of Democracy. We need to have representatives and an executive body. Nothing can really exist in it's pure form. Communism as Marx envisioned it would have probably lasted 10 years tops.
Meh, the idea of a "pure form" of any social-political typology is basically nonsense. A society is either constituted within the fundamental terms of a given social typology, or it isn't; it's either communist, or it's not. These are categories which we abstract from concrete social and political realities, they aren't some transcendent Idea which a given society participates in to a varying degree.
(Edit: By way of illustration,
A triangle is either a triangle, or it is not a triangle, as illustrated on the left. There isn't a "pure triangle" which other three-sided, three-angled shapes resemble to a greater or lesser degree, as illustrate on the right. So too with social formations.)
Pre-"Communist" Russia and China also hadn't exactly Capitalist economies.
EDIT: These countries didn't even had a bourgeoisie of any significance at the time of revolution.
You can't really discuss whole countries, let alone ones as big as Russia and China, in as sweeping terms as this. The industrial cities of Russia and China were all thoroughly capitalistic by the time of the revolution (or in China's case, "revolution"), and although they didn't contain a particularly prominent bourgeoisie, that was because of the degree to which investment was conducted by foreign capital and by the state, rather than reflecting any non-capitalist nature on their part. Only the countryside was pre-capitalist- or perhaps "proto-capitalist", in many places- and that's exactly Bordiga's point, that the historical function of the Stalinist state was to permit the rapid penetration of rural society by capitalism and so to establish capitalist social relations there without either having to wait for the slow and unreliable plod of history on the one hand (á la Bukharin).
Actually, the fact that nobody ever tried Communism Marx´ style might give you a clue about the viability of that particular utopia.
I'm curious; what is "communism Marx-style", and how does one go about "trying" it?
