I am genuinely a fan of Ezra Klein (at least on issues unrelated to Israel, on Israel I largely respect his point of view but disagree with it) but this is such a copout!
1) “Well you keep telling us that our political beliefs make us racist, so I guess we’ll just be racist” is just not a defense of racism! You’re still choosing to be racist!
2) Antizionists claim that their objection is not that Israel is a Jewish state specifically, but to its actions and/or to it not being a binational state (“a state of all its people”). To address the second part first, there just isn’t a constituency for that. Even when both sides trusted each other (which at the moment they don’t) Jews wanted a Jewish state and Arabs wanted an Arab state, and members of the other group would at best be a minority with certain guaranteed rights (and let’s be fair, a wide swath of both groups weren’t that enthusiastic about guaranteeing the rights of the other group). This is why the 2SS has been so fashionable, because it gives both sides a little bit of what they want that they could (hopefully) live with.
Now, coming back to that first part, if their claim was that their hostility to Israel was due to its actions (and/or their objection to ethnostates) and not its Jewish character per se, then why have antizionists allied themselves with people (or even been the people) saying Jews’ ethnogenesis is not in Eretz Yisrael (or it’s irrelevant), Jews are not an ethnocultural group but a purely religious one, Israeli Jews are primarily or entirely European (this one isn’t just racist, it’s objectively wrong), Jerusalem and other Jewish holy sites aren’t holy to Jews (or their holiness has been superseded by Muslims and Christians), Modern Hebrew is just badly pronounced Arabic, etc. None of these arguments is actually relevant to Israel’s actions or even to its existence as a “Jewish state”, they’re just racism used to argue a Muslim/Arab supremacist point about how Palestine should be properly a part of the Islamic/Arab world. For people who purport to be binationalists, supporting (or being) Arab/Muslim nationalists would seem to be counterproductive!
(the actual article isn't much about Israel or antisemitism, if you were curious: https://x.com/admcrlsn/status/2043328262428869087)
