Well, whilst I would not normally talk of my beloved mother in such terms, I was "pushed through a vagina somewhere in Scotland" and virtually all of my relatives - sister, son, nephews, nieces, grandchildren, in-laws - still live there. I visit them every year and still feel totally 'Scottish' as well as 'part-British'.
I'd love to have had an opportunity to vote in the referendum. However, WR, have you any concept of the vast administrative task that would have been necessary in order to 'discover' Scottish people still with a 'live' connection to that land, so that they might vote? Given the diaspora of Scots over the generations, the cost would probably have dwarfed the National Debt!
Accordingly, the way it IS being done is probably the only rational way in which it COULD be done.
