I think the whole vote is one not based on Scotland v’s England or not wanting to be British. It is about the same thing that drives up the UKIP vote. It is about being ruled rather than being served, it is about being told that Islam is good and we must tolerate their evil religion, it is about the government’s of this world being more answerable to the great leftist movements (see UN/EU) or the biggest banks and businesses, it’s about having new moralities forced down their throats - it is in fact a vote against where they find themselves in the world. If I could vote my State (South Australia) away from the rest of my country in the self delusional belief that it would turn back the clock to something I know was once better then I would do that. I can’t - the Scots might think they can - I think they will be disappointed no matter the result of the vote!
In theory, maybe, but the kind of people who run political parties in Scotland and the kind of people who run political parties in England are the same kind of people.
You could say that Irish independence was a great step forward for freedom and self-rule, but in recent years it seems like Ireland's politicians have tended to be even more pro-EU than Britain's.
Split the UK up into halves and each half will be weaker and more dependent on the European Union -- Scotland almost certainly more so than Britain.
