There's none that hate their fellow countrymen as much as a nationalist.
The reality is, polls have shown the biggest reason for voting 'no' is a love of Britain. A positive choice for them.
Anyway, I've been predicting a Yes since it was announced, no matter which side I was veering to. I remember the Arab Spring, when all came out for change. It's much more inspiring but not necessarily best. Mind you, the polls do show a No consistently leading with a high probablity of "shy no's" (a phenomenon most associated with "shy Tories" - they always do better than the polls as people feel intimidated to say they vote Tory, despite them being the largest party in England for the GE and over 1 in 4 voting Tory/Ukip in Scotland for the EU election) but I'll be voting 'no' and I've never been on a winning side, despite being a floating voter that has IIRC voted for six different parties in my lifetime (SNP, SSP, Green, Lib Dem, Labour and, if it counts, Independent if you're wondering).
My big hope is, whether Yes or No, Scotland accepts it and unites behind their people. I suspect that will happen with a Yes vote. But will Yessers agree to bury the hatchet, accept the result and move on with the choice of the majority in Scotland in the event of a No?
A lot of Yes supporters seem to be fueled by a very strong anger and hatred.
I have found this to be a common denominator of "Nationalists" in all the countries I have lived in. They are angry with their lot in life and Nationalism is an escape and target for their frustrations and hatreds. It seems to give meaning to a life that had no meaning or direction before and so they embrace it with a born again zeal and fanaticism that becomes divisive, intolerant and bullying and dismissive of non-believers.
I too hope that whatever the outcome of the referendum that Scotland will move forward peacefully and united.
