“Actually Rashi speaks about a nassi hador (is it leinei kol Yisrael?) “Yisrael nikraim Moshe uMoshe Nikra Yisrael ki nassi hador hu kichol hador ki hanassi hu hakol”
Remember from chitas
Along those lines I say The Rebbe, because The Rebbe took his responsibility as Nassi HaDor and was there to help every Jew who needed help weather bgashmius uvruchnius.
Many Jews (not just Lubavitcher) streamed to The Rebbe for yechidus/ dollars etc”
You can call the Rebbe with whatever title you want, but it seems unreasonable to compare the Rebbe to Moshe Rabeinu. For many reasons, but for one, Hashem appointed Moshe Rabeinu the position he had, not a group of people, and not because many Jews met with him for dollars or yechidus.
While you might hold the Rebbe in high regard, claiming that he shares the same level as Moshe Rabbeinu in terms of being recognized as the Nassi of the entire Jewish nation doesn’t seem accurate.
