Being a prisoner in Auschwitz-Birkenau was a nightmare; the 2004 Indian Ocean earthquake and tsunami was a nightmare; the German bombardment of London, the bombing of Dresden and the subsequent firestorm, the atomic bombs exploding over Nagasaki and Hiroshima - all nightmares; the fire in a house in Nottingham last night in which a mother and her two children died - a horrible nightmare.

Brexit is just politics. Calling it a nightmare just means that you're a spoiled, middle-class liberal who has had it so easy all your life that you think that not getting your own way for once is the end of the world.
