Menachem shmei claims that “he” holds that many Tzaddimim after Malachi etc had Nevuah. No he doesn’t. What he means is that the Rebbe said this and since every word the Rebbe spoke was Torah Misinai Menachem accepts it. Just as Menachem accepts that all Jews will be redeemed by Moshiach even though this contradicts the Gemara. The Rebbe successfully took away the free will of his Chassidim by forcing them to accept his every word as Nevuah.
