One thing that clicked for me in this is the fact that UNWRA has an interest in identifying people as refugees, presumably a temporary status which includes a right to either re-settle or to return to where they came from rather than stay where they are. And I can see why many Israelis might find this problematic.
On the other hand, I don’t see how the “right of return” claimed by Palestinian refugees and their relatively immediate descendants is an “ideology” that requires “destruction” any more than that claimed by the multi-generational descendants of the Jews who were expelled from the same land 2000 years ago. Or how “destruction of the ideology at the heart of Palestinian identity” would be interpreted by the people in this podcast if the word “Palestinian” were replaced with “Israeli”.
