As we move increasingly closer to demographic equality, a whole new dynamic of consent approaches. I would be horrified if the constitutional future of Northern Ireland was decided by a 50% plus one voting arrangement. The idea that there could be such a spectacular change in constitutional arrangements because of a majority of 1% on either side and that ten years from now the pendulum could swing back in the opposite direction is a matter of concern. It must go deeper than that. It is for this reason that words like "consent" are so important.
