//I think you are being either disingenuous or deliberately mischievous (or a little of both)//
I think you are too, NJ, by implying that the Irish don't want a border as if they would be happy with the North and the South under different trading agreements. I don't think that is the case. The Irish to my knowledge want a trading agreement between them and the North, which of course would be between the EU and the North, and which would effectively put a border at the Irish Sea.
