" #Jews carry history differently.

For most peoples, #violence against their group is episodic. For Jews, it is cumulative. #Pogroms, #expulsions, #forcedconversions, #massacres, and the #Holocaust are not separate chapters. They are read as a long, unfinished sentence. This does not mean Jews live frozen in trauma. It just means that the past is not safely archived. It is present tense. #Jewish memory is not nostalgia. It is vigilance.

So when a Jew is murdered in #Bondi, or on the streets of #WashingtonDC or #Israel or #Manchester, #England, or anywhere, the Jewish mind does not ask only, “What happened?” It also asks, often unconsciously, “What is this a continuation of?” That question is not paranoia. It is pattern recognition shaped by centuries of experience.

Moreover, Jews have a moral architecture that centers an ancient teaching that all Jews are responsible for one another. This is not just a saying. It is a demand."
