may be all. It isn't necesarily 'even the major issue, either, I don't think'
but it probably is a fairly important one because many people I think- and with some justification- regard left groups with a little suspicion and this can even spill over into hostility.
So it is really important to show in practice that we are interested in building joint action, interested in fraternal debate amongst not only the left but a section of workers in struggle and that we are not just twoing or parroting a party line.
I'm not sure how much this can be sorted out on a blog but I think it would be good to have some or at least work towards some definite proposals.
