Ian, that is probably because it is quite natural for working class, 'socialist' folk to have certain 'far right' opinions.
That's a very good point, Fester, and that's exactly how the National Socialist party in Germany gripped power in the 1930s.
I suppose the worrying aspect of the election of Corbyn is that it's a symptom of the country becoming fractured into extremes, once again. As things go Osborne will succeed Cameron, and I suspect he's sightly to the right of Mussolini. For a blissful while UK politics had become centrist but no longer, I suspect. We don't learn, as a population, do we? Divisions over race, religion, wealth, beliefs - they've all been the cause of conflict - sometimes bloody conflict - throughout the world. Seems that's exactly where we're heading.
