Don't believe this crap.
It is common for far-Left groups to co-opt Jewishness for any cause you can imagine.
Jews for Jesus.
Jews for Palestine.
Jews for Christianity.
Jews for Gay Sex.
Jews for Transgender.
Jews for the murder of all Jews.
This "Jews for" thing that the Left is doing is overplayed. There is no way to know if even a single, solitary, person at any of those 'Jews for' rallies is even remotely Jewish. It is just another propaganda medium.
