Firstly, they just had a referendum a few years ago. They need to wait for several decades before they have another. The UK government has no obligation whatsoever to allow a referendum. That they did allow one shows how remarkably civilized they were about it. Very few other countries would have allowed a free and fair democratic vote on the issue.
Secondly, the Scots voted against independence and according to polls, even more of them are against independence now than voted for it last time.
Well said. We only have to look at Spain vs Catalonia.
