I wonder how it feels to be a unionist these days. There was a time when, at the mention of a united Ireland, unionists (and a considerable swathe of ‘nationalists’) recoiled in horror or dissolved in laughter. There were even ‘nationalist’ politicians in the south who called on Sinn Fein and others to get real, focus on the bread-and-batter issues, scrap irrelevant talk of a united Ireland. But what was once seen as a binary choice - bread and butter versus a united Ireland - has quite suddenly become one and the same thing. And this has happened, compliments of our new friend Mr Brexit.
