I say let the scots have a referendum, it's all well and good hearing from the SNP, let's see what the scottish people want though. Personally, i believe staying in Britain would be the better option for them, however, i don't mind if they leave. At least i won't have to pay their taxes then.
They're in the UK, anyone who pays taxes pays for the UK. Scotland is a large drain on the UK budget, which means tax payers in the uk who don't want to separate have to pay more to keep them afloat.
