rise above politics by descending to their level

As 'descending' is a little pejorative so lets instead say meeting them eye to eye. Who? Well primarily traditional Labour supporters, but in effect those who can be swayed. There are two main threads of argument for/against independence.

First; we are better off in the Union/independent. In this context better off is generally regarded in an economic sense. This can only be proved on both sides by statistics which are generally either unavailable, unreliable, unfounded OR outright lies. In any case people will generally self select the data they want to fit their established viewpoint. Arguing on this basis tends to entrench views as people dig in to defend their beliefs; see next

Second; union/independence is a moral issue. I believe/have faith that the union/independence is the right thing to do. Without shifting this position all the logic, reason and facts are just going to be bashing away at the rocky shores of intransigence, true the sea will eventually turn them to sand but I for one do not want to wait x million years.

What to do?
