I spent 4 years getting educated at a Scottish university, "free". In my 4 years I never got abuse for being English. Great people, I've far more in common with the Scots than Brexit-voting wankers in the industrial heartlands of England and Wales.
The Scots are more left-leaning than their English counterparts but as a small nation of 6 million they don/t have the delusions of grandeur that affect half of English people. There are many smaller nations than Scotland in the EU so there's no fundamental reason why they shouldn't thrive...
