I think its a recognition of reality. Overwhelming majority of Jews support Israel in way way or another. Most of the "anti-zionist Jews" aren't really against the existence of the occupation they just want to "end apartheid" because it looks bad and is unsustainable for occupation. Like those protestors earlier this year realizing that the more their "Jewish State" desecrates Al-Aqsa, the more likely the Palestinians wipe their "Jewish State" from the face of the earth. As Khaled Barakat in a recent interview stated, a lot of them are just upset about their captured cousins and they wouldn't be nearly as energized if not for that.
The tiny fraction of Jewish community actually supporters of Palestinian liberation will recognize facts pointed out by user @frauddogg@lemmygrad.ml and would shut their mouths about how Ansarallah survives one of the most brutal siege of modern history.
Edit: Almost every Jewish institution and organization on the planet is connected to the occupation. Let's not fool ourselves.
