did not Ireland leave?
The only obligation on the scots is to live with their decision.
What you bring up here is what becomes of the minority of loyalist Scots in the event that the bid for Scottish independence wins: If polls are accurate, the split is almost 50/50 and that means a huge minority facing a slim majority.
Do the loyalist Scots now become some angry Scottish version of Northern Ireland if 'Yes' wins? I'd sure be inconsolably angry if I were a loyalist Scot living in Scotland and knew that half of the Scots I encountered on a daily basis decided to drag me along with them on this sketchy new journey of an independent Scotland. With plans they can't articulate, questions they cannot answer, and positions they can't rationalize: They'll have to vote for it to find out what's in it.
Political academic scientists have speculated that at the time of the American Revolution some 80% of Colonists were in favor of independence. The 20% of loyalists remaining are whom we now call Canadians. That's what happened after our War Of Independence, but where do 50% of loyalist Scots go? They're captives who've been unwillingly dragged along for the ride into hardcore socialism, make no mistake.
