Indeed.
Claiming that criticism of Zionism is anti-Semitism is claiming that the things that Zionists do are typical Jewish things to do. In other words, that it’s a Jewish trait to:
- See themselves as inherently superior to all others not of their ethnicity
- Be extremelly racist, especially towards Muslims
- Think that those born in specific ethnicities are “vermin”
- Violently attack those of ethnities they see as “vermin” for no other reason than their ethnicity
- Steal from those of ethnities they see as “vermin”
- Calously murder civilians of ethnities they see as “vermin”, including purposelly murdering children
- Rape civilians of ethnities they see as “vermin”
- Starve to death civilians of ethnicities they see as “vermin”
- Commit Genocide
- Run child sex honeypots for the purpose of gathering kompromat
and more.
In summary in light of the acts openly commited by those Zionists who have the power to freely act according to their ideology and the support of other Zionists for those acts, calling criticism of Zionism anti-semitism is the same as saying that the Jewish People as a whole are basically modern day NAZIs with different ubermenschen and untermenschen than the original NAZIs.
Thus implying that the Jewish People inherently and as a whole think and act similarly to NAZIs is indeed
The most antisemitic thing you can say
It was always a White Jewish Supremacist Colonialist project anchored on a late 19th century Western way of seeing the World (the same perspective as Europeans with “colonies” in Africa were they often forced the locals to work for them - a form of Slavery, not Chatel Slavery but still Slavery - or Canada’s Indian Residential Shools).
Whilst most of the West actually evolved away from that (even if recently some of that was reversed), Israel was a bubble of White Jewish Supremacy (more White than Jewish, as shown by how the Israeli Authorities treated Black Jews from Ethiopia) stuck in time and with whatever little evolution toward Humanist values they imported via the minority of immigrants they had from the West (the majority by a wide margin of immigrants to Israel came from Russia and the Middle East, not the West) being reversed by amongst other things a Press and Politial environment that purposelly fed “Fear of the Other” and extreme Racism disguised as righteous anger at “violent” Palestinians (at times even openly called “vermin”).
So yeah, not only was the Nakba a display of the dominant values in Israel (as is their overtly ethnically discriminatory Constitution), but since that time the country has not evolved away from that original perspective on other human beings and those racist late XIX century and early XX century views on human beings.
(Whilst, for example, Canada ended Indian Residential Shools and that is now looked back as a bad thing, Israel is right now commiting a Genocide in Gaza and Lebanon even more deadly than the Nakba and Israeli Jewish “settlers” are openly commiting a Pogrom on Palestinians in the West Bank with the support - sometimes activelly so - of the Israeli Police and Military)
