I'm not quite sure what the solution is here. The majority in Scotland voted to remain, I get that. Sturgeon came up with her own Brexit plans which was to remain in the Customs Union and Single Market. Now call me a cynic but I'm sure she came up with this plan because a. she knew that England dosen't want to be part of the customs union and single market so, knowing that her plan would be rejected, she could throw her hands up and say "well I tried, they won't listen, time to go Scotland" and B, remaining in the SM and CM makes Scottish Independence easier without the threat of a border with England. I agree that there is an onus on the Government to make sure that Brexit is either a success or at least not a crushing faliure to appease places that voted remain and stave off calls for a second referendum within 10 years.
And anyway, this issue goes beyond Brexit. It was the SNP who won Holyrood in 2011, five years before the vote! Whatever has led to this rift between England and Scotland must have occurred sometime between 1987 (the last election where the Conservatives had many seats in Scotland) and 2010. The SNP was rising in Holyrood elections all through the 2000s, so in the grand scheme of things, I don't think Brexit is that important to the Scottish Nationalism debate, but it's certainly a factor. Personally, I believe that whatever caused Scottish nationalism to rise is the same reason that caused Brexit. A feeling of disentachment with the Party political system, but living in a long era from 1979 to erm, now, where the oppissition is not a credible choice so the only alternative is to keep relecting the same party for long, long years. Therefore, there's been a lack of intelectual diversity in Britain for a generation-producing the same dissapointment, only in power because the alternative is unthinkable. The English and the Scots are clearly both fed up! You could argue therefore, that maybe Scotland and England should become their own countries, but that suggests that the socio-political disenchantment in this country is directly because of the existence of the Anglo-Scottish political union. Which it isn't. The problem is that the political system prizes political dogma over truly understanding the country outside its own political circles.
