Of all the things to accuse SNP - jingoistic? Really? Either you know nothing about Scottish politics or you don't know what the word jingoistic means. The SNP vocally opposed unnecessary wars that the UK government has engaged. They support unilateral disarmament, support the UN, and have only very reluctantly accepted a policy of remaining in the NATO alliance as long as Scotland doesn't need to harbour weapons of mass destruction. In fact it's the SNP's opposition to the Iraq war and nuclear weapons that attracted many people to the cause, me included. One of the most popular independence slogans during the referendum "Bairns Not Bombs" was plastered all over cars and houses. A rather curious marching call for so-called warmongers.
As for the other slurs they are also the oppsotive of the truth. The Yes campaign was outward looking, pro-immigration, pro-EU, positive about Scotland's place in a British family of nations. The anti-English slur is a canard so old a patently untrue that even Scottish opposition parties have given up insulting the intelligence of the Scottish people by invoking it.
About the Billy Connolly quote: I think it perfectly exemplifies the small mindedness of a few who still exhibit the Scottish cringe, or the idea that there's something abnormal or dangerous about the notion that a country should govern itself if that country happens to be called Scotland. Plus it's well worth remembering that Billy Connolly was not just opposing Scottish independence in that quote. He made that comment during the referendum for devolution in 1997 and was strongly opposed to Scotland having any parliament of any kind. Which is a position so unpopular and extreme now in Scotland that not even Scottish Tories advocate reversing devolution.
The BBC was extremely biased against the independence movement during the campaign. I saw this myself especially during the last days of the campaign when the Yes movement created a carnival atmosphere in Scotland that was barely reported. Also barely reported was the violence of the unionists in George Square the day after.
