The Star of David on the Israeli flag is insidious propaganda, conflating a religion and a diasporic people with Zionist settler-colonism.

Be careful, some of them support zionisms. There was two incidents of real estate events promoting property sales in the West Bank inside a synagogues

Donate to Sikh kitchens. Core tenant of their religion is simple acts of kindness for the sake of being kind. They take everyone in at Sikh kitchens. Even cities in Texas and CA that like to ban feeding the homeless can't do shit about these kitchens because it is recognized as a part of their worship.

I'm partly repeating what others have replied, but when a nearby synagogue hosted a Zionist corporate event, some of the protesters alongside us were members who normally worshipped at that synagogue and felt disgusted.

And, for an extreme example of anti-Zionist Judaism, here's some Hasidic Jews over in London, including their Rabbi, publicly burning an Israeli flag: https://www.vice.com/en/article/anti-zionist-orthodox-jews-flag-burning-protest-109/

“The whole state of Israel is not legal from the Jewish viewpoint,” said the flag burning’s organizer, Rabbi Elhanan Beck, adding, “The Messiah will not be [Israeli Prime Minister] Netanyahu.”
