It's not a question of a majority and a minority.
There is no unitary state called "Eire". There is an island, on which there are two nations, neither of which want to belong to the other.
The obvious solution is two states. Any non-two state solution is fraught with problems, and the failure of either side to design or accept a unitary (and acceptable) state in 90 years makes the possibility that this will occur in the future quite remote, IMO.

You may be right. Why not settle the question democratically and put it up for an all Ireland vote? It seems that would settle the question.
