Haven't read the full thread but here's the rub.
The democratic will of the people, demonstrated through a referendum, was to leave the EU.
Ireland, North and Republic, also held a referendum in 1998, in which more than 70% and 90% respectively agreed to implement the Good Friday Agreement. (This is their democratic will). The UK government was a signatory. It is an International Peace Treaty.
The Brexit referendum was incompatible - the GFA depended upon the common arrangements between the two states. It could only ever breach the terms of the GFA. If the UK wanted to leave the EU it should have sorted this out first.
The GFA cannot easily be renegotiated - it was a masterclass in negotiation, took many years and followed thousands of deaths. As a child I lived in the middle of it - I saw people die before I was old enough to even know what it was all about. My children have been spared that distress. It has changed my life and my children's futures. This is massively important.
I am an Irish citizen. I am therefore, by default an EU citizen. I was born and continue to live in NI. I do not now, and never have, owned a British passport. It is my right, as asserted within the GFA, to identify as Irish, British or both. I respect everyone's choices. My choice impacts on no one else, but Brexit impacts on my choice.
