The example of Northern Ireland is not a good example either, to that of the UK mainland. Being Irish, I have a good knowledge of Ireland's complicated history, but in short, as we know, since the 12th century onwards, Ireland has been routinely colonised by England, it's native citizens and their culture despised and repressed. One obvious example is that of how it was seized for its economic importance due to its agrarian infrastructure, and importance that resulted in continued food exportation druring the Great Famine, food that could have saved the lives of countless thousands. In short, genocide. Before partition, Ireland had to endure centuries of brutal repression and as well as developing an enduring sense of injustice, it also developed a distinct loss of esteem and self worth. After partition, as we know, a religious apartheid was put in place and upheld for decades by the British, hence the appaling violence on both sides during the Troubles, as a result of deep and complex socio-political roots going back hundreds of years. The 'English' part of the UK psyche has no understanding or concept of this, and as unjust as it may be, that is the prevailing collective psyche of the UK mainland, existant in the central power structure, and this is reflected in the media and is generally accepted in England. As for our own Civil War, the resulting split in communities and families and the violence that ensued had unshakeable roots in religious belief and a sense of that combined with duty and allegiance, whichever side you took. Obviuosly, that particular context could never apply again.
