Generally speaking the Brits are decent, sober, sensible, folk. But every nation has their breaking point. What happens if Scotland goes? Most people in England couldnt give a farthing for Northern Ireland, except in a general “all part of the union, innit” sense. Scotland is different, larger, more integrated, more important in every way. Lets say they go. Then add the permanent Tory majority which is emerging, propped up on the right by some variant of Ukippery. Add in the realisation that yep, the Tories lied, Labour is eating its own entrails, again, and there is no succor from a Europe to whom we gave two fingers.
What does it take to get anger from simmering resentment?
