Give enough people the opportunity to say how much they dislike foreigners and they will say how much. The temptation is too great. Give them privilege to express displeasure at papistical ways and they will express displeasure. Violently, if necessary. Give enough people the power to hide on their side of the fence and you can stay on your side of the fence. Give enough people the excuse to deny their neighbour’s existence and they will deny. Old allies turn enemies and plot amongst themselves. Let enough people vote in June and eftsoon they’ll grumble about the winter of discontent.
