One of my closest friends works for newcastle uni and is a deep corbyn supporter. He regularly bemoans the hampstead/islington version of socialism and sees them only in the frame of useful idiots... The Bolsheviks had the same ideas, of wiping out all the other socialists and the Islington set itself, despises the white working class, as much as the democratic party does in the united states.
Your right the working class is divided at every level, which is rather the intention one would assume, to create a powerless majority.
As long as they all vote and the next Labour government builds enough council houses for the people, invests in education, invests in UK manufacturing and business and does not let corporations run rough shod over our rights, then I am not that fussed.
If they can get the railways renationalised and a strong UK SOE Energy company too then that would be a bonus. ;0)
