Faith, my comment was to your sarcastic "fixed that for you" quote. Don't you think it was a tad smart-arsey?
I agree MaryZ, it was smart-arsey, but I'm fed up of seeing sweeping statements being made about 'brexiters' as if we're all one big blob of stupid & nasty.
I 'fixed' the comment by adding 'some' [brexiters] and 'some remainers', that's all.
Wrt the UK being able to have a hard border at Calais, but not between NI & Ireland - that's because post Brexit the UK can decide for itself what borders it has, and whether they're hard, soft or non-existent. (Wrt goods & people)
If post-Brexit UK doesn't want a border at NI, going to Ireland, it doesn't need to have one - it's up to the EU & Ireland whether they** want a border going the other way though, and there's the sticking point.
Movement of people is not a problem, post-Brexit UK can decide what/how/when/who wrt border control of people coming in - the chances of Ireland & NI becoming the new 'Calais jungle' are probably zero. And the CTA pre-exists EU FoM anyway.
Movement of goods, however, is the sticking point as far as the EU is concerned - my point has always been that the border problem cannot be resolved until a trade deal is being discussed - only then will it become clear if there is indeed any need for a border at all.
Regardless, if the UK doesn't want one, it is not compelled to have one - but the EU may insist that Ireland has one with NI.
