Unless they physically detach themselves from the rUK as part of the post-referendum settlement, then Scottish people will always be British, seeing as Scotland is very much on Great Britain. What they won't be is citizens of the United Kingdom.
(But I digress. We seem to have meandered off topic again.)
Never mind the scots detaching themselves, the UK needs to remain an island nation! I propose, in the event of a yes vote, we dig a several miles wide trench along the border and flood it- thus separating the separatists and maintaining naval security.
And if the mainstream parties won't accept this, I will endeavour to create my own in order to see my goals accomplished.
