Well, it's a different country. That's usually how democracy works. We wouldn't be taking any democratic powers from the rest of the country (the opposite is true).
Yes of course, and in a very basic sense, the smaller the democracy you live in, the more your individual vote counts for. It would also clear up the question of Scottish MPs being able to vote on matters only affecting England. My point was just that, with a huge number of people in the rest of the UK extremely dissatisfied with the clique currently running the country and no opposition worthy of the name, it's understandable that people here aren't thrilled about a change that could move the political centre of gravity even further to the right.
As you say, it'll be decided by Scottish people voting, so from your POV it's neither here nor there, but it's not unreasonable that English people have an opinion on it.
I take it you'd like to be able to decide what oil prices OPEC sets, or what kind of fishing policies the Scandinavian countries have. Unfortunately it's a different country.
Huh? I can't say either those things particularly concerns me.
Scotland may be a country but it's also part of the sovereign state of the UK, at present. Saying "Scotland should be a separate country because it's a separate country" is both circular and, for now, untrue.
