As the dust settles and we all try and make sense of what has just happened, one thing is crystal clear; we live in a fiercely divided nation.
Young versus old, rich versus poor, have versus have-not, people with qualifications versus those without, it's stark. London and all the major cities voted one way, as did Northern Ireland and Scotland; the rest the other.
Much has been made of the generational divide, older voters tended to support leave while those of the young who voted tended towards remain. As for the older generation who voted to leave I wonder, what would their parents think? What would the generation that grew up in the 1920s and 30s make of their choices?
My grandfather, Albert Mann would have been 100 this year. He was the son of Jewish immigrants to London's East End. He and his brothers made and sold cloth caps at Petticoat Lane market. They lived in a ghetto and daily faced the kind of anger and abuse many immigrants suffer in today's Britain. Albert lived through the rise of Mosley's Blackshirts and fought them at Cable Street.
Then as now, populist figures offered simple answers to complex questions.
Albert served in the RAF during the war while my other Grandpa, Bernard, served in the army. Along with the rest of their generation, they witnessed the destruction and misery wrought by the Second World War. That generation fought against the dark forces of fascism, an ideology that demonised difference. At great cost, they won and what they experienced changed everything.
At the end of the war, from the wreckage, they built the National Health Service and the post-War consensus was born. After the sacrifices of the war years, there was no going back to the inequality of the 1930s.
Yet that is precisely what has happened. As a friend told me today, the biggest shock about the leave vote is that it is such a shock. We have become so estranged from each other that we didn't see this coming. As ever, the real villain of the piece here is that same inequality our grandparents thought they had overcome. Once inequality takes hold, it's easy to stir up hatred of others and intolerance, the perfect breeding ground for fascism.
We cannot give in to hate. We must solve these problems together, just as our grandparents generation rebuilt the country after the war. And we're going to have to fight with all the tenacity of our grandparents' generation to fix this mess.
Love and unity are what will save us now.
