I'm an outside American who hopes to visit Scotland. I am probably a little biased as I write this because I'm listenin to the Classical Station and currently playing is a lovely piano concerto based on variations of "Rule Brittania". . .(The Rand Variation by Ferdinant Raes)
ANyhow, I can see an argument for Scotland remaining with the U.K. should the U.K. maintain its independence from Europe. Scotland already has a membership in the European Union and as a member of the U. K. life is administratively easier and a Scot can dream of being head of the U. K. government and culture can mix more or less freely with less bureaucracy.

On the other hand, should the U.K. join the E. U. as a full member, adopt the Euro, etc. why shouldn't Scotland want to be and equal member of the E. U. to England, hence independent of it?

Overall, I am tending with the NO voters because I think bigger democracies are stronger and better for all concerned, the more that divisiveness is fostered, the better for the plutocrats who can turn governments against each other and take advantage of them.
