On the 'Platformist Organisation in Glasgow' thread in Organise, John. said:
To be honest I can see that there is a gap for such an organisation to fill a niche - that is an anarchist organisation which gets involved in struggles as an organisation. Which is something I've not really seen in this country.
Thought this discussion deserved a thread of its own instead of derailing the other one.
Personally, I'm not so sure how useful it is to have specifically anarchist organisations involved in struggles as organisations, I'm not saying that anarchist organisations have no useful role to play (I wouldn't be in the AF if I thought that), but I think that as groups, anarchist organisations should limit themselves to acting as support networks and producing propaganda.
In fact, I'd argue that groups with specific ideological restrictions on membership (as opposed to your more obvious, practical restrictions, like kicking out fascists and total nutters), instead of groups which are influenced by class struggle ideas but are open to all working class people, can be divisive and put people off getting involved.
