What have English, Welsh and Canadians got to do with this? It's a Scottish issue. Let them make their decision, and then live with it. No-one else's business but theirs.
The trouble is, Roadster, the decision affects us in the rest of the UK to a very great extent. Just one thing which has been mentioned many times, but say you were a Labour supporter (I'm not btw!). Scottish Independence would remove approximately 40 Labour MPs from the Westminster parliament at a stroke, and see Labour's chances of getting back into government vanishing into the distant future (hooray!).
Similarly its not something thats going to be just decided by "the Scots" (this has already been covered). Only those resident and registered to vote in Scotland (including thousands of English, Welsh and Northern Irish) will be able to vote. On the other hand Scots living outside of Scotland wont have a say. This may come as a surprise to US citizens, who can vote postally wherever in the world they may currently reside, but that's the way Wee Eck wanted it, so that's the way it's going to be!
