Thinking about it, I suppose one of the more interesting points that's come up here is what we want revolutionary organisations to look like, and how we want them to reflect the make-up of the working class.
Thinking about our fantasy football ideas of what a communist organisation "should" be like, I suppose I would want it to reflect the composition of the broader class as closely as possible, not just in terms of the obvious stuff like age, race and gender but also in terms of things like employment status. Having the kind of labour movement focus the AWL argue for would presumably mean (trying to) function as an expression of the best organised sections of the class, which I suppose is quite a different ambition.
Following on from this, perhaps it's healthier to take an "ecology of organisations" view, and accept that no single organisation is going to be able to represent the class as a whole, but a group like the AWL can act as a more-or-less sectional expression of the most organised fractions of the class, and a group like Plan C acting as an expression of those sections of the class who have more precarious and insecure employment situation?
Don't fully know where I'm going with this, but it seems like a possibly more fruitful direction to think in than just arguing about whether "social strike" is a useful phrase or not.
