I know I've said this before in these discussions, but I don't see what the difference is, if our politics are based on our economic interests (which they are for us). The only difference might be for example if Solfed did not allow members of the bourgeoisie to be members, but the AF did (but of course practically that wouldn't make a significant difference anyway)
You know we didn't invent the distinction right? It's a distinction that has been made throughout the workers movement for at least a century. It has nothing to do with what you think in your head. Every leftist through to the crudest base-superstructure tankie would stress the political and economic are inseperable, then advocate separate economic based unions and a political based party. Unless you're saying that organisationally the CNT or FORA are 'the same' as the CP or KAPD because of their members thoughts?
Now it might well be that AF members think it is the role of revolutionaries to try and organise class conflicts along direct action lines. That's great. But that means you're advocating political-economic organisation, not that it's all the same. It has little to do with your slightly bizarre fixation with SolFed's membership criteria! It's about whether revolutionaries should seek to organise collective direct action themselves, or leave it to separate economic organisations, be they trade unions (platformists and others) or spontaneous transient groups formed in struggle (workplace resistance groups as 'informal tendency', pannekoek's spontaneous organisation etc).
You resigning from SolFed then?
