Full disclosure: I’m irish, live in Scotland, and pro-EU and pro-Scottish Indy. I voted accordingly in the referenda.
The Indy Red was indeed divisive, but hardly toxic. The outcome was indeed decisive and, while I’d like to see another Indy Ref at some point, it shouldn’t be done too soon. Unless there’s a tangible change in terms of course.
There are far, far more divisive topics out there than Scottish independence. I’ve got fond memories of getting involved in campaigning for Indy, which was quite a lefty liberal inclusive movement (although was portrayed rather differently by some aspects of the media.
I don’t view myself as a nationalist at all. I’m against borders in general, and view the idea of separate insular nation states as backward. I was pro-Indy because of the lefty liberal Scandinavian ideals espoused by the movement, and the idea of Scotland embracing the EU and become an outward looking country.
But I digress.
There’s a real and valid case for second Indy Ref, particularly if Brexit proves to be the sort of clusterfuck that is now looking likely. But I’d worry that a quick turnaround on a second referendum would kill the independence movement dead. So we’d need to be careful about pushing it through without an obvious change in public opinion in favour of independence.
