Now who's bitter?
Its probably pointless but I'll repeat it for the sake of form: Scotland is over-represented in Westminster. You do not have rule imposed upon you from London. In fact the situation is quite the reverse. Scottish MPs may vote on matters which concern only English voters but not vice versa. And Scotland has its own Parliament. The democratic deficit is tipped in completely the opposite direction to the one you suppose, yet I have never heard a single English person complain of living under Scottish political oppression. You may not have voted for a conservative Government but I didn't vote for a coalition and I didn't vote for 13 years of Labour. In my constituency we have never voted for a Labour MP yet we must live under Labour governments. Scotland is no different because while part of the UK it is not and has never been a separate state. You are a region within a single nation. You do not get to choose which part of the national democratic process will apply to you. If you wish to change that state of affairs in your referendum by all means do so but spare us the colonial martyrdom act because it is factually nonsensical.
You ask why the devo-max carrot is being dangled but you have answered your own question. The Labour party is desperate to retain its grip on Westminster politics which is why at the eleventh hour they have wheeled out the cyclopean sociopath from Kirkcaldy to plead on their behalf. Their behalf remember, not ours. Mr Cameron is wheedling and whimpering because, ostensibly, he doesn't want to be the PM who "lost" the Union, as if it were his to lose. In reality he doesn't want to lose the Tory leadership and the ensuing general election.
I find their blandishments as distasteful as you do. More so, in fact since as a subject of the Union they make them in my name but without my consultation or approval.
Just get on with it will you and make that Yes vote win.
