A few things on this:
It's not just David Cameron talking down to the people of Scotland, Westminster Governments have been talking down to the Scot's for a very long time.
Clan warfare was mentioned, not quite sure how relevant Scot's killing Scot's is.
"Think of the number of dead from inter clan warfare, which has lasted for centuries!", I'm hoping the "has lasted for centuries" was a typo, since the clan wars are long past.
"I'm curious. Is this something the English Parliament, is accepting of" There is no English Parliament, this reinforces the opinion that many outside of the UK see English as British and British as English. Wouldn't you want to be away from a view like that?
"effectively allowing a reversal of British laws" Scottish law is different from English/Welsh law, in fact Scotland has an entirely separate judicial system.
Regarding the "NO" campaign, all we are hearing in Scotland is an almost constant litany of "you can't manage without us" and how resource poor Scotland doesn't contribute as much as it gains from the UK and needs to be part of the UK, you can't count on Oil revenue, can you give a 15 year financial forecast? No? well, you can't seriously expect the people of Scotland to vote for you.
To that I ask, if Scotland is such a big drain on the UK, wouldn't it be better without them? Wouldn't England, Wales and Northen Ireland have more?
Westminter factors in Oil Revenue in it's projections, so why can't an independant Scotland.
No one can provide an accurate 10 year forcast, so why is the "NO" campaign demanding a 15 year forecast?
Not forgetting the latest from Westminster, no to a common currency. Right now we technically have a common currency type arrangement, English and Scottish money are not the same, they are different currencies that are generally accepted by each country, although trying to spend a Scottish note South of the border isn't easy.
So I personally don't see why that would have to change, but I'm not a politician out to score points over the other guy.
The above are large arguments, but I believe it's the small things that will influence votes more.
Things like the face of the BBC's money experts, Paul Lewis not being able to get the name of the Scottish Finance Secretary correct. Calling him "Martin Swinney" instead of "John Swinney", not only did he get it wrong, but from what I was able to see that day, no one picked it up.
As for the "YES" campaign's everything will be sweet and lovely, you'd have to be a complete halfwit to even think that would be the case.
Of course Scotland will have to apply for EU membership, but then so does any other country. Assuming that would be the best way to go, not all continental European countries are in the EU and the couple that aren't, don't seem to be up the creak without a paddle.
Just a couple of my initial thoughts after reading some of the comments.
