We have all grown up in the shadow of the Holocaust, knowing that we are the bits of the family that survived because we had the sense to 'get out in time'.
My grandparents left many relatives behind them in Poland and Ukraine - none of them survived the war.
We have all grown up knowing that the only reason we were able to be born was because our ancestors were sufficiently alert to recognise when Jew-hatred, always bubbling away beneath the surface, reaches a critical mass, and it's time to GTFO.
In 2018 I went with my dad to visit the town that his dad came from in eastern Poland, and I also visited Polin museum in Warsaw, which is the history of the Jews in Poland (amazing place). The 19th century antisemitic materials I saw there gave me a real shock -they were in many cases almost indistinguishable from the cartoons and tropes that were being shared in 2018 on Twitter and Facebook.
In 1906 there was a pogrom in my grandfather's home town - we saw the bullet holes in the walls of the houses, and photographs of the piles of corpses in a book that has been published about it. My family left shortly after that. And glad they did because during the war the family home was one of the houses that marked the edge of the ghetto in that town. The majority of the Jews remaining there were shot dead in the town cemetery - 3000 men, women and children were shot dead in one day. This is one of many thousands of similar stories.
Those that survived that massacre ended up in Madjanek and Treblinka, and died there. The town was at one point more than half Jewish. There are no Jews left there at all now.
It happened in Britain in the 12th century, in Spain and Portugal in the 15th, in Poland in the 19th, in Germany in the 20th, et cetera et cetera et bloody cetera. If we weren't on alert to look out for the signs that tell us it's time to pack our bags, none of us would be here. Which would clearly be preferable for a large number of non-Jews.
