With the current focus on negotiations over Brexit and the Irish Border, the Government’s partner, the DUP, have been very loud in their objection to the argument that an open border with the Republic of Ireland should be the primary objective of negotiations. They fear, we may suppose, that in order to achieve this outcome, the Government will agree to some kind of internal UK border running down the Irish Sea, which, from a DUP perspective, would be a dilution of their status as British.
What has been given scant attention in this discussion, is that a majority of the Northern Irish population voted in favour of remaining in the European Union. It follows that significant numbers of Unionists voted to remain. The DUP therefore, in their stance on Brexit, represent a minority Northern Irish opinion.
An arrangement which is acceptable to a majority in Northern Ireland should be the objective of negotiations, rather than an arrangement which suits only the DUP. Needless to say, this presents a problem for a government reliant on the support of the DUP to stay in power.

https://polldaddy.com/js/rating/rating.jsI believe that a United Ireland will benefit both communities that voted to remain in the European Union as it will provide more economic stababilty and will also create more jobs, career opportunities, and a borderless island which benefits all the citizens of Ireland.
Whilst I agree with this, I remain concerned about the transition to Irish reunification and the possibility of this being undertaken within the terms of the Good Friday agreement, that is, majority support for this on both sides of the border. Even then there is a potential for difficulties if a small minority in the North of Ireland resist change, possibly violently. Whilst one should not readily submit to such a minority, I remain open to reform of the UK Constitution, which could make remaining in the UK Union more acceptable in the short term, and therefore would allow the probably inevitable re-uniting of Ireland to take place at gentler pace. This post offers one suggestion. https://carruchan.wordpress.com/2021/01/29/saving-the-union-a-job-for-a-superhero-nah-its-just-common-sense-but-is-it-worth-the-bother/
