Self serving nationalist and arrogant and incompetent could be said about the Scottish government and as for being dragged out of the EU that could be said of leaving the UK as well .I'm not sure I entirely agree with that. Being dragged out of the EU by a self-serving English Nationalist government has strengthened the political case but the financial case still has to be made. Big questions still need to be answered. If an independent Scotland did join the EU (far from certain) then what happens to the border with England? And if we didn't join the EU, then a lot of the reason for leaving our current union has gone.
I think what the Scots need to bear in mind is that the government in Westminster won't always be as arrogant and incompetent as the current lot.
The reasons the snp wanted to stay in the EU are the same reasons they should stay in the UK, IE free trade open borders free movement etc
