This thread seems to have descended quickly, but to answer the original op from a northern england perspective, 'England' is not a homogenous country much more than 'UK' is.
Plenty of northern english people have sympathy with the notion that the current government is far too London-centric. Many think that the rest of the country matters and its needs have been systematically ignored by the British government for far too long. Our problem is not the Scots, any more than it is single mothers, the disabled, or the poorest on ZHCs. It is all of those, principally southerners, who keep voting for and supporting this disgustingly hypocritical self-serving greed-obsessed political establishment.
Too answer the pps who rolled out the old claim that London has to be central because it bankrolls the rest of the country: it's the other way around, all resources have been sucked down there. Further how long do you really think London could survive on its own without the food, water and energy supplied by the rest of the country? Don't talk wet (or do, rather).
It is the long term refusal of our political establishment to recognise that the whole country contributes, along with it's willingness to for e London's 'rights' to exploit the rest of us, that has created this disaffection in the rest of the country, not the Scots.
