The problem is that different groups want to leave the EU for different reasons.
So long as these reasons are kept vague there is no problem but the moment people try to describe, which they rarely do, how they see the future out of the EU all hell breaks loose.
We know how things stand inside the EU but outside ?
Surely the onus is on those who want to leave to explain, in detail, how they see the future ?
Once again thanks to John Blackmore from one of our SY2E groups.
