@Moon @Hyolobrika It’s understandable that they would believe that, given the context in which those authors grew up (i.e. after having like a third of them wiped out in the span of about 5 years). It’s not at all a given when thinking long-term, though. Cultures tend towards integration over time.
If we’re talking about Orthodox Jews that truly believe in their own superiority (I mean in a “divine right” sense, not just based on stats that show they do tend to be pretty successful as a group) and thus consider “whites” to be beneath them, then you can say they’re not white. But at that point it’s self-fulfilling, since your refusal to integrate is what causes the lack of integration.
