How is it fair or justified for a minority to try and keep a nation in constitutional limbo as they attempt to achieve their aims? By the same logic if Scotland became independent we should then keep having referendums to rejoin the union, if the rest of the UK would have us back......
If I remember Alex Salmond himself said a referendum would be a once in a generation decision so around 25 years would be the soonest another could be held, if there is sufficient call for one.
