it's not beginning from a position of good v bad working class - it's looking at reality and seeing what things are either a help or a hinderence to pro-working class politics & organisation, if as a result of that, the analysis adds other things (i.e. behaviours, tendencies etc, rather than people as such) to what is traditionaly seen as 'bad working class' i.e. scabs, police, bailiffs - then so be it. Let's call it for what it is and the impact it has.
What's the reason for not focussing on behaviour (that you say) can not easily be defined though? That's what in my opinion we should be focused on. And just because it may be difficult to do is no excuse for not doing it and focussing on easy things. Do you really think we need a debate within our communities as to whether we tolerate rapists or murderers?
Again, why do you insist on putting morality as a driving factor here, when it's been explained that it's not a process that starts with morality, but one that starts with hard nose materialist reality looking at what kind of behaviours are detrimental to working class communities, life within them, confidence, and the chance of those communities developing a progressive pro working class political outlook?
What's the point being involved in pro-working class poltics if we focus on the easy to define and obvious and shy away from attempting to even analyse, let alone do anything about, the albeit complex & prickly yet equally destructive tendencies, manifestations & behaviours that if allowed to further take root has the potential take any chance of an emboldened & confident working class political organissation of the table for generations
