From a distance I would guess this is not about being Jewish - by birth or by religion. It's about being one of the people of the state of Israel and explaining that by saying who is not one of the people (or not yet). Of course it's complicated via the law of return including people who are not technically Jewish, but who have privilged right to migrate and become Israelis. But when are they accepted as one of the people of the land, rather than some migrant who will parent Israelis?
