Scotland's "Nationalism" is about gaining independence and actually becoming a nation, not about violent and misguided idealism.
In fact, Alex Salmond (leader of the Scottish National Party, the majority party in Scottish Parliament) has come out for more liberal immigration policies, to encourage positive economic immigration[0]. Compared to the UK government's increasingly tough stance on immigration[1], and the rise of right-wing parties such as UKIP and the BNP, I'd much rather live in a small, liberal nation like Scotland.
