I accept that 62% of those who voted north of the border voted to remain. That doesn't automatically equate to leaving the Union, though it may be a sound argument for a second ref.
Freedom of movement, fine if, on the balance of negatives and positives, that's more important that whatever the alternative may, or may not, be.
Specifically what worker's rights, and what human rights, do you fear losing? The EU is certainly no respecter of workers rights. The code is Capital over People, and anyone who thinks otherwise has not properly studied the judgements of the ECJ, and has magically erased the evisceration Greece from the equation.
Tariff-free trading - the rUK is Scotland's largest export partner by far, and accounts for nearly 50% of her exports. The figure for the rEU is under 15%. I don't know what percentage of Scotland's GDP that equates to, but I don't imagine it is an enormous figure.
The thing that I completely fail to grasp is the fact that Scotland, as an independent member of the EU, will be a small regional country effectively beholden to decisions made to suit the dominant Franco-German axis. As part of the Union her representation in the Westminster parliament runs to 55 of the 650 MPs, whilst in the EUP it will be I think 8 to 751 MEPs. In addition to her representation - already disproportionate when set against the size of her population - in the UK Parliament, she has an increasingly powerful Parliament of her own. Scotland's representation in Westminster has included a quarter of all Prime Ministers and goodness knows how many Cabinet members in the 20th century alone, and her historical influence in the institutions, businesses and the global reach of the UK going all the way back to the beginning of the Union has been enormous.
Then there are the practical questions over accession to the EU. How long will it take, will Scotland retain the Pound in the interim and thus have no decision over monetary policy, how will she square the 6-7% budget deficit when the EU requires less than half of that figure, how will she manage without the rUK contribution to her coffers over the 3-4 years minimum that it take to accede to the EU, how will she deal with having to accept the Euro, will Spain or one or other of those Flemish parish councils veto her accession and so on? How will the country cope with a hard border with the rUK?
