No, subsidiarity is the key. There's room for several levels of government from local through regional to national and international; the key is to define the areas of responsibility in order to avoid contention and to ensure that each level is representative.Fair enough, as I have stated before, I would have voted to Remain if we as a country were willing along with every other of the 26 countries in the EU, to totally abolish their own parliaments and have just one over all Parliament with local area councils dealing with local issues.
Having two Parliaments constantly fighting each other, with all the costs involved, is just a recipe for disaster. So would you be happy to concede all Scottish Parliament decisions to the EU and abolish Holyrood, turning the building into flats for all the boat immigrants ?
The major source of contention that you reference above is driven by decisions being made or blocked in Westminster by governments that have no mandate in Scotland.
I'm sure you are aware of this but for those unfamiliar, it's worth highlighting that Scotland has not voted for a Conservative government since the 26th of May 1955.
