The "United Kingdom" is quite a misnomer isn't it. No king and not very convincingly united.
If our Scottish friends go independant they will clearly no longer consider themselves part of the United Kingdom and presumably (?) will expect to be referred to as "Scottish" and not "British". Will they then accept the island on which their land sits being geographically referred to as "Great Britian" or will they expect the land mass to be renamed to reflect their determination to be non-British? And will the name "Great Britain" even still apply, since the "Great" part refers to geographical size and not political ego? The same then of the wider "British Isles" as well.
What will become of the Union Flag (aka Jack)? Will the UK remove all trace of the St. Andrew's cross and if we don't will Scotland file some legal demand that we do so?
Having been an expat for many years i have noticed a very clear propensity of Scottish Brit expats to tout the Scottish flag in clear defiance to the Union and the Union Flag. On the back of their cars for example. In conversations with Welsh and Scottish expats over the years i have found in general the Scottish to be far more vitriolic toward the English than are the Welsh. Also much more so than the English are toward the Scots. Can't comment on Irish having met very few. I have found the devisiveness of the Scots quite tiresome, though i respect their right to opinion and viewpoint. These are just my observations, not a reliable survey, but clearly a broad swathe of Scots do yearn for independance though i do wonder if it's more to do with pride and romancing Scottish identity than a thorough awareness of the probable political and economic consequences both now and long term (be they good or bad or both). I say if the Scots vote for independance then fine, let them try it and with out any bad blood on either side. If later all realize it wasn't such a great idea i'd also welcome a future reintegration. The whole thing will be complicated, expensive and arguably not prudent but what the hell, give it a go if that's what they want. Trouble is, it's not what they ALL want...!
