Hi, leftist Israeli here!
Yes, there is plenty of truth in those tags. Unfortunately.
From Israel's founding through the mid-70s the predominant persona / propaganda / idea of the "good" Israeli was ~
Secular Jewish farmer, any sex but must be strapping-strong and educated. A resistance fighter who killed Nazis in Europe by the dozen and now works to tame the Holy Land. Hates "diseased" marshes. Hates "dirty bloodthirsty" Arabs. Hating the British is optional but recommended. A brave Sabra!!
a "bad" Israeli was any of the following:
not Ashkenazi (ie not white-passing).
disabled in any form whatsoever unless it's a Cool War Scar from killing Nazis and even then you better not have any "trauma", gross
talks about the concentration or death camps. ever
religious freaks only allowed if they hate Arabs and swear to keep to their freak selves in seclusion
unwilling to pop out as many kids as possible
Israel also worked hard to lionize the actions of ALL Jewish / Zionist resistance movements. Some of them *were peaceful* and *did NOT call for attacking Palestinians*. But Israel has worked hard to put only militant groups front and center of its history lessons, such as Irgun and Lechi. The IDF has always been lionized, in spite of various peace and tolerance movements over the last seven decades.
Ironically, this attitude absolutely crippled historians' ability to document the Holocaust. Tens of thousands of survivors were shamed and bullied into silence. So many "gen X" Israelis speak of how their parents one day "just broke down" in their old age and started talking about their Holocaust stories. As well as stories of life before. Whether as a cosmopolitan Berliner or shtetl Polani. Whether from a shift in culture allowed them to speak, or they simply needed to come clean before death, I dunno. But for every story shared, we must have lost scores. It's a travesty on top of travesty. Shame on Ben Gurion and his cadre.
So yes, "never again" meant "the Jewish people will never be weak again because Israel will defend them*" (*only the ones that are Good) for decades.
There were major social shifts after the Yom Kippur War and also in the wake of the anti-war movement in America. Also, the demographics of Israel changed -- Sefaradi and Yemenite Jews were here for decades already, as well as Palestinian Jews who had been for centuries. But they finally were able to gain political capital and force their way into the national conversation.
In recent decades, Holocaust survivors' role was changed from "embarrassment to be locked in the attic" to "noble, helpless martyr (support the military of this will be YOU!!)". In Zionist circles, they get trotted out once a year to schools and synagogues to talk about the most traumatic experiences of their lives before being sent back home to a dark room and empty fridge*.
*I'm exaggerating a little. But not as much as I wish. We care for our senior citizens and we love them. But the Israeli government willfully neglected Holocaust survivors for many decades. Through the 70s at least, if they didn't have a family to support them, most of them did live and die alone in abject poverty.
I do beg of those who are appalled -- please do be appalled! But Israeli society has been changing and continues to change. We're trying so hard to dismantle the machismo and jingoism baked into the culture. Trying to integrate our communities in places like Yafo and Haifa. Welcoming refugees from places like Sudan and Somalia rather than locking the south-western border.
The Oslo accords, the assassination of Rabin, the rise of the modern Likud -- there's more recent history. Netanyahu has been a disaster for the cause of peace and justice, but it can be done. I truly hope to see a peaceful and united Palestine/Israel in my lifetime.
To the modern moderate Israeli, "never again" has returned to the liberal weak-ass idea "The Holocaust* will never happen again" *by which we mean that authoritarianism and fascism is okay as long as we can pretend it isn't there!! or use it as an excuse to invade a foreign country!! There's more layers, but the core of "never again" is *waves hand* meh.
To a leftist Israeli "never again" means "no genocide again, not on our watch, not here, not anywhere". We stand for Gaza, for Palestinian equality and independence, we have stood against the fascism in our own government for manyyears.
As much as I want to argue for the many good qualities of Israel (which do exist. don't you dare argue that an entire country of people is 100% All Evil Zionazis. allow for complexity for Satan's sake). It is vital to acknowledge the evils of our past so we may better understand and fight its expression in the modern day. I've had to do a lot of work to unlearn my rightwing upbringing. And I've spent uncounted hours reflecting on my place in Israeli society, my past in the IDF, my future as a leftist activist. History is full of dark and light and colour all. It's never too late to learn from it.
