I think it's got something to do with the role of the vanguard party. You've got the Bordigists, as super-Leninists, at one end of the party spectrum (like this lot who have just emailed this to us) and the Pannekoekians, who reject the whole concept of the party, at the other. This lot seem to be near the Bordigist end more so, perhaps surprisingly, than the ICC.I think that arguments about the precise day that the Bolshevik revolution degenerated also come into it.
