LOL, do you actually know any Jews in real life, or are you just theorizing? There is no “Jewish ideology”. There are a bunch of people whose parents were Jewish and who believe all kinds of different things. People will never “all just get along”. But the valid basis for disagreement is not “that person is black, and I’m white” but along the priorities and values dimension. My biggest criterion for who I want to associate with is not race/ethnicity but are they based or someone who just believes what he’s told. That’s it.
