Zionism fundamentally conflicts with Liberal ideas of oppression and hierarchy. Its hard for them to understand that a historically (and to a lesser extent currently) marginalized group (Jewish people) could perpetuate the very oppression and pain they experienced. Israel is also the "civilized" Western country that "supports queer rights and neurodivergant people" (fun fact: Israel has a special military branch where they make vulnerable and often mentally disabled people commit horrific crimes against humanity). In addition it conflicts with the Liberal idea that Judaism is a "progressive religion" leading to cognitive dissidence (can personally not confirm, Judaism is just as regressive as any other religion. I would know, ive been Jewish my entire life).
