Well Sturgeon and the SNP basically have the "Okay, so the referendum didn't go our way this time. We can do it again in a couple of years. And a couple of years after that. We'll keep having them until we get the answer we want." approach to it all.
Also, much as we love the hilariously bad history of Braveheart, and the more respectable Rob Roy, the thing that a lot of people overlook these days is that Scotland was separate for a chunk of time, and they went bankrupt and pretty much sold the country to the English. Look up the Darien scheme, that's what had a large impact on causing the Acts of Union to occur. So you shouldn't take the firm image of "The English were conquering bastards that took our lands" into too much account when talking of the United Kingdom and Scottish independence.
