Unionism paying the price for never trying to win over Catholics

If I was a real unionist, what might I do to try to secure the Union? I would be anxious that something needs to be done. For the first century of Northern Ireland’s existence, it had pegged its hopes to demography. So long as there was a Protestant majority and so long as Protestants could be encouraged to believe that the Union was theirs and in their interests, there was no problem.
