NEW YORK – Billionaire hedge fund manager Daniel Loeb lashed out Sunday at Hasidic journalist Jacob Kornbluh after Kornbluh defended New York City Mayor-elect Zohran Mamdani, whom Rep. Elise Stefanik described at the Zionist Organization of America gala Sunday night in New York as a “dangerous antisemite,” “jihadist,” and “communist.”

Kornbluh, a political reporter, posted on X that Mamdani “is not” any of those things, prompting Loeb, founder of Third Point LLC and a major donor to pro-Israel causes, to respond sharply: “The capacity of certain Jewish individuals for self-hatred no longer surprises me. My diagnostic tool to identify such people is a simple question: Can you name the Parsha of the week and briefly summarize?”

Loeb linked to the “Simchas Torah Challenge,” a Torah-learning initiative, suggesting religious study as a “remedy.”
The exchange drew attention online, highlighting divisions within the Jewish community over how to confront Mamdani, a democratic socialist whose positions on Israel and Gaza have sparked controversy.
Loeb, a prominent Jewish philanthropist who has frequently criticized progressive Jewish figures for what he views as moral confusion or silence in the face of antisemitism, has an estimated net worth of $4.6 billion.

It’s about time Kornbluh gets called out.
Thank you, Dan
Calling Mamdani a communist is inappropriate in the same way as calling Stalin a bad father. You’re implicitly downplaying the magnitude of his antisemitism by not letting it headline in your criticism.
Well deserved! I hope Jacob does teshuva.
It is incredible that 30% of so called Jews voted for this hitler reincarnation. You reap what you sow.
hes Satmar I dont understand why they love Jew haters
Good I’m glad the real Jew !! The true YID. has the money and is giving it to real. Jewish causes as opposed to leftist KAPO who give two causes like SOROS that are anti-Israel anti-Jewish and anti-Charedi.
What’s progressive about him? How many Jews in the former USSR like Stalin? How many were communists? There’s nothing progressive about supporting Democrats.
how ever many millionaires are opposed to mandani,
bottom line is he won the elections. Now that hes in he must be dealt with.
you cant ignore “the elephant(in the room)
soon to be sitting in city hall calling the shots
He’s the covid Benedict Arnold who can forget him. Hopefully that rodef rasha gets what he deserves
We are supposed to live modestly and not run after the American ostentatious life style. We are meant to be a Kiddush Hashem. “Lama tisrouu”
The comments here are pretty creepy, many in the frum world became nuts
Mamdani IS A HITLER. WE JEWS NEED TO UNITE AND FIGHT BACK. WE NEED A RABBI KAHANE AND A JDL. RABBI DR. BERNHARD ROSENBERG
Why does his opinion matter because he’s a billionaire??????
Respecting another person’s opinion is a keystone in free speech and unity in society.
Not sure how his god given wealth makes a difference in this article
i don’t think this is fair – there is no evidence that kornbluh hates jews or wishes us harm. “never attribute to malice that which is adequately explained by stupidity.”
Someone tell “Elise” that you can’t be an Islamic jihadi AND a communist at the same time. Mutually incompatible beliefs. Her sloganeering is for the dumbest only. Like Trump.
Who voted for Mandami:
1. Very assimilated Jews
2. Super religious like Satmar, Lubavich, etc
Why ?
Money for yeshivot
Who are you kidding? Why are you opening you mouths as if you are in charge? You are not!!! Were supposed to be living as yidden who keep Torah and Mitzvos. No one told us to get into this fight over a western democracy that calls itself Jewish. We are supposed to be waiting for Moshiach and not get involved in politics and warfare.
Will you guys calm down already??? You don’t want to believe you are still in Golus! So there is a new mayor in NYC. He is Muslim? Good! Maybe he can be less of a liberal.
Another billionaire vs Momzeri. LOL
The fight that the zionist leaders got us into with the Muslims does not serve us well at all!!! It has nothing to do with the real goals of Klal Yisroel. We have absolutely no Nevuah for these wars. We are letting ourselves to led by Apikorsim for over 70 years. WAKE UP!!! THIS IS THE REAL DANGER.
