//If it comes to it, the EU will set up the border,…//
Really? Does the EU have a border force, then? Does it have the authority to use that force in one of its member nations?
//Wasn’t the whole Brexit vote about taking back control of our borders. That is what Farage, Vote Leave and LeaveEU said Many times before the Referendum//
//We take back control of our border by declaring we are not going to have any controls?//
You (and others) keep spouting this drivel, gromit. You always forget to add the little bit which is of most significance: Brexit is about taking back control of our borders as we see fit. For many years the UK and Ireland have seen fit not to impose border controls on the island. This stretches back to 1923 when the Common Travel Area was set up following Ireland’s secession from the UK. This has remained the position apart from during WW2 and the “Troubles”. The current Common Travel Area also includes the Channel Islands and the Isle of Man (neither of which are part of the UK) - a sort of mini "Schengen Area" if you like, but one of the UK's own choosing. So to say that once we have left the EU and are "taking back control" the border must suddenly be imposed is utter nonsense.
//And now the same lying hypocrites are saying they don’t want to defend our Border with the EU, they will leave it open, and it is up to the EU to do it (and pay for it).//
See above. The UK has no wish nor any need to “defend our border with the EU”. It does not expect the EU to do it and does not expect the EU to pay for it. It is the EU that is insisting on “defending its border” in Ireland, not the other way round. What they do, how they do it and who pays for it is entirely a matter for them. Personally I have no interest in how Ireland or the EU patrols their borders. You are either continuing to be confused by the issue and seem to believe that everybody else is or you are being deliberately obtuse.
