"To state the bleeding obvious once again. THe UK can't have whatever border it likes. It has to reach agreement with people on the other side of the border."

Graphic illustration to disprove the above:

Eire - X to XX - Border - Northern Ireland

Where X = vehicle and goods checks, XX = checks on persons (Passport Control)

Everything on the Eire side of the border is dictated to the Irish Government by the EU Commission as the Republic of Ireland is an EU Member State and MUST abide by rules set by the EU Commission.

What happens on the UK side of the border is decided by the UK and as shown above that can consist of nothing (OUR choice - which is the whole point of leaving).

"Biologist" Steve can be as proud as he likes but what he has no right to do is to attempt to say in a discussion that "You cannot contradict me because I've got a degree in (whatever) and you must accept what I say". Which is basically what he did on that thread - Iains however stood his ground and subsequently demonstrated, with relevant links to back his argument up, that he did know what he was talking about.

The "Irish" have been fighting the "Irish" since the beginning of time (Note to Gnome and to Raggy in this context the phrase "the beginning of time" is merely an expression - it does not mean literally from the beginning of time). The very first thing they embarked on having won their "independence" was a civil war.
