You're being intentionally obtuse now. If you can't see why an open border is vital for the continued peace, and why removing it would place tension on a peace that took decades to achieve, then you've already made up your mind.
I suppose I should have expected it when you blamed the EU for the self-inflicted woes of Brexit.
I'm not in any way slow to understand, not in this case anyway.

I didn't say that, and I'm not even going to engage your straw man.
And I did not blame the EU for Brexit woes, I made a pretty basic statement of fact that would probably cover any negotiation, one which was intended only to signal compromise -- hence why the UK did not leave entirely -- not woe or blame.
