In case you wanted to see Ismail from /marx/ take:
"In the first post, the person points to Bukharin's "communist left" faction within the Bolshevik party (which was real enough) and emphasizes it "was not formally opposed to Lenin. In fact, it was Leninist…"
It was precisely because it was not Leninist that Lenin struggled against it. The poster isn't revealing some sort of suppressed history; everyone who knows even a little of the first decade of soviet power knew Bukharin leaped from the ultra-left to the right.
In addition, far more left-communists today are influenced by "council communists" like Gorter and Pannekoek, who started off as supporters of the Bolsheviks only to declare that party "state-capitalist." Not to mention other left-communists who (however wrongly) counterpoise Luxemburg to Lenin and claim the former as their own. Obviously what Lenin derided as "left-wing" communism is going to look different in 1918-1922 than it looks a century later.
Lenin did indeed praise Bukharin's 1915 work on imperialism, although in that same 1915-16 period he was arguing against other positions held by Bukharin. But to say Lenin's own work on imperialism was merely "an outline/summation of Bukharin's" work is asinine; when Lenin wrote the prefaces to his own work, he tipped his hat to J. A. Hobson, not Bukharin. I also don't see how all this is relevant, considering that by the poster's own admission there was as yet no "communist left."
As for the second post, Bordiga certainly claimed to uphold Lenin, but practice showed he was no Leninist, precisely due to his sectarian position on the unions, toward parliaments, and on various other issues where Lenin's own writings (as well as Marx's and Engels') can be shown to be in blatant contradiction to Bordiga's.
Claiming that the "Italian left was the first and largest mass communist movement" in Italy is misleading (Bordiga circa 1919 had not yet fully developed his ultra-left views, and he was just one of multiple leaders of the party) and irrelevant. When (for example) the American Communist movement was formed it largely subscribed to the IWW's dual unionism strategy as well as a belief that revolution was imminent and the communist party ought to operate underground. It took the Comintern to overcome these views, just as it helped overcome ultra-leftism in Italy. When Bordiga was left with his own devices, rather than belonging to a party larger than himself and which came to reject his increasingly sectarian positions, he ended up creating an irrelevant sect (just as there were a few American communists who defied the Comintern and continued leading an underground existence, fading into obscurity.)
Attributing this process of overcoming such tendencies to Stalin and the Third Period is erroneous; as early as 1924 there was a campaign within the Comintern for the Bolshevization of its member-parties, struggling against traces of social-democratic, syndicalist and other deviations. Bordiga himself was removed from the PCI's leadership in 1923.
I think it's a case of the pot calling the kettle black. Not a unique phenomenon in history.
That the "Dutch-German left was also Leninist, up until the mid-30's" seems wrong as well. As early as 1923 Gorter was claiming that the peasantry "made the whole Bolshevist party its tool. It was like an elementary power which forced the Bolsheviks — even men like Lenin — to stand against the class from which the Bolshevists had sprung. . . . Communism vanished like a ghost into the background, and capitalism re-appeared, even stronger, in the foreground." He further complains that "Lenin and the Third International have talked the proletariat into a combination with the capitalist nationalism of Asia" and that, "Many fake principles have penetrated from Moscow to Western Europe and North America. This has been largely through Lenin’s book called The Infantile Diseases of Left Wing Communism."
In other words, just because these people didn't view Lenin as a wicked evildoer doesn't make them Leninists.
I give credit to the poster for acknowledging Liebknecht and Luxemburg were generally at odds with left-communist positions. But again this is no suppressed history; "Stalinists" have been pointing this out since forever."
