In 2014 I would have agreed. You cannot pretend Brexit is just run of the mill politics though.
Watching English politicians tell Scots they can't have a referenedum on their own country's future is typical of where we are though. And not a good look for England if we want Scotland to remain part of the UK.
It's not really for me to say whether Scotland should or should not leave the UK. I think the goalposts have been moved sufficiently that they are entitled to another shot, should they want it.
