Lenin refers to stick bending.
Tony Cliff spells out the meaning , " I believe there is an important and unsatisfactory way of attempting to explain Lenin’s purportedly elitist formulations in WITBD within today’s socialist movement, which is to claim that Lenin is simply “bending the stick.” This formulation seems to have been at least largely introduced by Tony Cliff of the British Socialist Workers Party in his important book Building the Party. In Building the Party, Cliff writes, “At every stage of the struggle Lenin would look for what he regarded as the key link in the chain of development. He would then repeatedly emphasize the importance of this link, to which all others must be subordinated. After the event, he would say: ‘We overdid it. We bent the stick too far,’ by which he did not mean that he had been wrong to do so.”
) At the 1903 Congress, it is Martov—who in this same series of meetings becomes the leader of the Menshevik faction of the Russian party—who says that Lenin “made a confession to us” that “‘the stick had been bent in one direction, and so we bent it the other way.’” Depending on which translation you use, Lenin may have also used the metaphor in the 1903 debates
The interpretation is that its a common russian expression, and they knew they were hardline and experimental… possibly too hard.
