The categorisation of SNP voters into Brigadoon Dreamers, Britain (England) haters and morons is a very apt classification.
I met a Brigadoon Dreamer the other day who had been a fairly senior manager of a registered charity (now retd.)
Confronting him with some facts e.g. separate Scotland getting taking apart by capital markets and short selling of the new Scottish currency failed to rouse him form the dream. "At least we would be controlling it ourselves , he responded" Of course ,that is pure nonsense and it shows you the mindset that's out there.
Given the 3 categories we must expect that opposing that mentality is paramount...either by Westminster saying a very final NO to another referendum, ,setting that bar so high e.g. 70%. or better still to turn the tables on the SNP and instigate a "devolution audit" to examine the state of affairs in devolved Scotland after 14 years of SNP mis-rule and as a pre-cursor to any further talks on devolution let alone on independence referendums.
In other words devolution has been a disaster and now time to turn the tables on the SNP and re framing the dialogue to " Sorry, but it just hasn't worked. A first example being the behaviour of that SNP group of cretins at Westminster and to highlight their ZERO contribution to that affairs of the United Kingdom. Why are they even there...at least their brothers and sisters in Sinn Fein stay away. Cut the travel costs tell them for starters just to send 1 representative,
