I think it used to be like that, and in some places might still be interpreted the same way. But there is much more going on and its not in isolation. In Wales and in NI especially, the maths indicate that the break-up of the Union is not that far off.
Those who want to retain the union need to get their head round the causes of the turbulence. There independent movements in a lot of small countries around the world that are fed up with the imbalances caused by the requirements of the 'nation state' - the information-centric a nature of many 'capitals', their parasitic absorption of scarce or high value resources, the unequal distribution of health, housing, employment opportunity and education. Its neither a uniquely Scottish, Welsh or Irish thing - indeed, it is becoming an English thing too in the Midlands, in the North east, in Cumbria and so on. The exact same process underpins much of what recently happened in the USA and frankly, if these matters are not addressed, there will be major other issues to contend with within a generation.
