We as, a group. seems to be avoiding the great truth preventing the forward motion of opinion. Scotland as a country has the right to decide it's future in or out of UK.
The arguments almost always descend to a confrontation between the emotional desire of Scots to see their country independent and the economic costs of that need. The two can never be balanced because one is a number and the other a thought, the size of each are not measurable.
In quandaries such as this it is the democratic custom to seek the will of the population and according to the outcome direction and size decide. We will not even approach a solution to this problem until both countries agree on a logical system of decision making, which we will never do. We are doomed to many years of pointless argument.
