Astonishing Culpability Hypocrisy and Malevolence.
Aside from the amoral, blatant and continuing enthusiastic land theft, the obvious self-misrepresentation of the Jewish community at large is stark and abhorrent. Are synagogues establishments where one practices a religion or zionist community centres, or both? How does a religious institution facilitate land theft and genocide? How is a zionist entity that sells stolen land a religious institution? Unless that's the religion. Unless that's the culture. If one is a self-proclaimed Anti-Zionist Jew who suggests that they merely practice Judaism or wish to be part of the culture and community while in opposition to genocide, look at what your community facilitates and endorses- openly. They intentionally obfuscate. They try to blur and establish self serving lines between religion and zionism, between rabid Israeli leadership and the sociopathic will of “Israelis” and most Jews across the world, between Anti-Zionism that still supports a “homeland for Jews” and true Anti-Zionism that supports its dismantling.
They slaughter and are complicit in the slaughtering of children. Unapologetically.
They slaughter children. Nothing happens to the citizens and officials who advocate for the slaughtering of children.
They shoot children. CHILDREN. And nothing happens to the soldiers/citizens who do it. For murdering children.
Any position offered by a Jewish person that falls short of rejecting all notions of superiority and favours condemnation of the Jewish state and its dismantling is repugnant and unacceptable. The time where “Living peacefully” with their neighbours might have been possible is, after murdering, raping, wholesale slaughtering of children and stealing land, over. Attending Jewish institutions including synagogues that do not overtly condemn “Israel” and support Palestinians is complicity. It's like adherence to a church that does not condemn the clergys’ pedophelia or the murder of indigenous children at residential schools, only larger scale and, hard to imagine, even worse.
There is a lot of talk about what constitutes being a Jew or not. I was born and raised one. Personally, I don't believe in the religion's determination of who is Jewish or not. Community, culture, upbringing, personal belief etc. all play a part in establishing identity. Some say a Jew can decide not to be a Jew but they are still a product of the above notwithstanding. What people live becomes part of who they are. Maybe being Jewish is purely a decision for some, I don't know or care much. I'm not one culturally, religiously, community or otherwise. The remnants of being a Jew are part of me. Does that make me one? Decades dead beliefs and membership in a community, upbringing and faith that I have for years eschewed. Am I a Jew? Is that person or this person one? Who cares? The salient consideration is whether they utterly repudiate the notions of supremacy and stand unequivocally against the Nazi stain of "Israel" or not. Can they look a Palestinian, Lebanese or Iranian mother in the eye and say "I utterly condemn the murderers, illegitimate state and people who did this. I am not of them. I stand with you."? If they can not say this they fail as a person, Jew or otherwise- but particularly as a loathsome Jew in a group of overwhelmingly loathsome Jews.

"The remnants of being a Jew are part of me. Does that make me one? Decades dead beliefs and membership in a community, upbringing and faith that I have for years eschewed. Am I a Jew?"
I would say, no. If you leave a cult, you're not a cult member anymore.
Nazi race science is nonsense. The old testament is nonsense.
You are free. Enjoy life 💖
