It's a hard call for SWP oppositionists whether to go to take a speaking platform at Marxism or not. Those going hope to use the event to get some arguments going. Mike Gonzalez, for example, has made his position pretty clear. I'm told that Paul Le Blanc is going as a critical voice. Those against taking invitations are concerned that whether you get a chance to raise the various arguments that arise from the rape allegation or not (and how will you get a few blows in if you are speaking on an unrelated topic?), you might end up being associated with the current CC. I think it significant that (unless I've missed it), Eamonn McCann is not on the program. Personally, I think it a good idea to attend, pick key meetings like Molyneux and the 'real' IS tradition and steam in hard there. But NOT to be an invited speaker this year.
