Jaruzel, I can't reply directly to you, but in fact a majority of all party supporters in Scotland voted Remain, so an analysis that focuses entirely on SNP strategy (whether true or not - I have issues with it) isn't going to explain it.
The most Leave-heavy party was the Conservative and Unionist party, but I believe they still voted Remain.
Maybe I was a bit heavy on the SNP influence as I have many family members in Scotland (from Borders, to the Islands) and they are all anti SNP. Regardless, my points about Scotland not being economically independent without EU subsidies still stands.
Really the problem is trade barriers. Independence is much easier if the rest of the British Isles are in a Single Market and Customs Union.
In fact Scotland would likely be a net contributor to the EU, given its GDP, so it's not an issue of EU subsidies. That is probably the weakest part of your analysis.
