Not what he meant, I expressed the thought accurately as being less claim. The African tribes are being debated by world Jewry regularly, many are accepted fully such as those he spoke of, some are also given provisional acceptance due to weaker history. That's mostly about outlier cases though, as well as about "degree of Jewishness". To the question of who are Jews when Jews are being persecuted by government, yes or no, they all qualify, and Christians don't anymore (not since the 300s).
