In case this makes you feel any better: some of the bravest, most decent, most human people I have had the privilege of interacting with have been Jewish Israelis!
The activists who, back in the 2nd intifada, came to help my Palestinian family during the olive harvest to protect them from violent settlers? Jewish Israelis!
The people currently raising the alarm over the exact same issue, over settlers, literally!, using the opportunity this all out war on Gaza has created to drive entire Palestinian villages away? Jewish Israelis!
The people speaking out that they have lost family - as recently as 7/10, who more so than them should be forgiven for lashing out in anger? - saying that they do not want revenge? Jewish Israelis!
I have honestly met so many great, generous, wonderful Jewish Israelis in my now 20 year involvement with this topic!
And, yes, I am more than familiar with what you are describing! After all, I was married to a Palestinian man for over a decade and spent significant time in the occupied West Bank - including a time of living there! I know perfectly well! But I think the point you make about it being "trauma" is really relevant here! I will never forget that day when three armed to the teeth teenagers and their armoured personnel carrier held me at gunpoint for over an hour. I was the tiniest blonde woman and, needless to say: unarmed - and they seemed utterly terrified of me. I was quite afraid they would shoot me out of sheer fear if I moved too suddenly. I understood something vital about this conflict that day: how deeply, deeply afraid many Israelis are!
Anyway, your post sounded so deflated, my main point was: Jewish Israelis include some truly wonderful humans! Maybe you feel like making contact with some of them? Might help the sense of despair a little!
