So ultimately you are saying it's the wrong type of democratic centralism, a "joke" version of democratic centralism? In which case I refer you back to that post where I addressed that a few replies ago.
Ok here's another example -
frogwoman was actually asking on this thread only yesterday whether or not she'd get into trouble for saying what she's said. Now when you've got members looking over their shoulder, worried that a bit of sincere and thoughtul criticism of their own party on the internet could get them in trouble, then I think that's a sign there's a definite problem within the organisation. That's not healthy y'know, people shouldn't be scared to criticise their own party, and especially not someone whose criticism has been thoughtful and considered.
I think these problems come from democratic centralism, it's an inheritance from some of the worst aspects of the Bolshevik party that have been fetishized and should've been abandoned years ago.
And I happily concede the SP isn't actually that bad for this, at least compared to other left groups, but it's hardly perfect, is it now? This shouldn't be happening at all in my opinion.
