One of my paternal great-grandfathers died at Ypres, and yet I don't hold that against anyone - what's done is done. Nothing can change that.
Most of my maternal extended family died either under the Soviets, due to the starving of Ukraine, or from the Nazi einsatzgruppen that swept through Ukraine behind the army. I'm a couple of generations away from that, too, and yet I don't hold it against anyone, or fixate upon my "victimhood".
Much of what goes on with the state of Israel with appeals to past historical persecutions are, in my opinion, nothing more than attempts to secure exceptionalism - "you shouldn't hold this against us, because we were so badly persecuted and traumatised" - well fuck that! We're human beings, and capable of growing beyond such childishness, and it seems to me that the state of Israel isn't keen on Jews doing so, because then a plank of modern Zionist thought - Jewish exceptionalism - goes out of the window, and a justification (actually an excuse) for appallingly murderous behaviour likewise goes out of the window.
