I do agree we should never forget, such a stain on humanity. I visited Israel back in the early '80s and always remember a group of older people on an adjacent table, beach side restaurant, their tattooed numbers, clearly visible. The horrors they survived.
On Amazon there is a film called "The Zone of Interest", which is about the Commander of Auschwitz, Rudolf Hoss and his wife, who were living in a cocoon of domestic bliss, raising their 5 children right next door to where thousands of fellow citizens were being systematically murdered. What bloody awful people, how did they ever become like that (not their children, they didn't know what was going on)
I abhor the re-emergence of anti semetism after all the historical ills that have been heaped on the Jewish peoples and now to conflate peaceful Jewish communities here and in other European countries with the ills being meted out to the Palestinians by Netanyahu's government.
