Well I suppose it is practical if there is a 310 mile long 15 meter fence topped with razor wire, and machine gun nests suitably spaced along it, that is one idea...although it might not go down well with farming folk who have one farm in both countries.
It might be practical to use drones and check points and random spot checks on workers, or everybody has an ID card, or is obliged to be chipped in the ear lobe or something, these things might be workable. Is that kind of stuff what you think brexit voters mean by taking back control of the UK borders?
If not that, then what others solutions might there be, the notion that something has to give because the circle can't be squared as it were is an interesting one, until one comes up against the notion that people in the Republic are those who have to do the giving to help along the brexit vote result from the people in the UK.
Not only do I have ideological issues, I have issues regarding how the hard border will impact people day to day.
A 'fudge' has been proposed, but a friend in Northern Ireland sent me this:
' I do not believe that a fudge is possible, for the very simple reason that WTO rules would make such a fudge the default position for the external borders of both the EU and UK in trade terms, post Brexit.
There has to be a detailed agreement to define the relationship between the the two parties, in both of their interests.
As for the potential for violence, I have mentioned that the PSNI are convinced that the presence of any customs infrastructure on (or near) the border in Northern Ireland would be a target for dissidents. It's precisely what has happened before on the border, and could reasonably be expected to happen again (the post on the border at Aughnacloy was destroyed by a car bomb in the 1970s and the gutted remanats remained until about 10-15 years ago).
The key point about the GFA is that joint membership of the EU was assumed in terms of the relationship between the UK and Ireland - just like breathing is assumed for any of us discussing this.'
The reason the people in Lincolnshire should be concerned is that until things improve the brexit referendum was a UK wide vote, and when they voted, they voted for something that impacts the lives of those who are called UK citizens in Lincolnshire, and in Cornwall, Wales, Scotland and Northern Ireland whether that suits them or not.
Indeed it is frequently said that those struggling in various regions object to decisions made about their lives by the remote metropolitan elite in London, yet that is what they have done themselves, made decisions about the lives of people miles away.
You ask why folk in Lincolnshire should 'prioritise' their agenda to be subsumed by those in Ireland who wish to travel freely to and fro, and my answer is that if you don't wish to order your priorities, then you should have a solution ready if your own priorities have a negative impact on others.
It is a bit like polluting the water upstream because getting rid of that waste is your 'priority', and not caring about what happens to the people who depend on that water downstream.
If that analogy has any resonance or meaning, could it be that the people upstream see themselves as superior to the people downstream in some way? Would that kind of attitude be a doorway into a racist, ignorant and tosser like perspectives?
