I once opened a speech by confessing to a crowd of Jews that I used to hate them. It was 2006 and I was a young native of Somalia who had been elected to the Dutch parliament. The American Jewish Committee was giving me its Moral Courage Award. I felt honoured and humbled but a little dishonest if I didn’t own up to my anti-Semitic past. So I told them how I’d learned to blame the Jews for everything.
