Dear Qwerty,
Instead of taking a step back, step up and answer the questions that were put to you. You are being more evasive than any Chabadtsker on this thread.
I didn’t notice any posters claiming that The Rebbe was coronated as Moshiach.
Around the time of the Six Day War there was a global campaign to discredit Rav Moshe.
Nothing in Judaism has been universal for a long, long time.
There were Torah Giants of infinite magnitude that were living in obscurity, especially in the postwar decades.
I think Rav Moshe and the Chabadsker Rebbe have met in person.
Nevuah is definable. But I won’t know exactly until I have a prophetic experience. Who accept as a Navi also has parameters. But it clearly is not foolproof. And it follows, that one can be a Navi with nobody knowing about it.
Nobody on this thread asked for you to trust Chabad. The question is, why are we so obsessed with Chabad’s opinions? You don’t seem to be able to answer for yourself. If I could talk for you I would say that you don’t have any of your own opinions on the matter. So you become Anti Chabad in place of anything worthwhile.
“Finally, how ridiculous is it to suggest that the Rebbe understood Pshatim in the Gemara that no one in the last 2000 years knew?”
It is very ridiculous.
1) The statements in question are not yet 2000 years old.
2) The Rambam makes an allowance for rejecting the sources about the messianic age.
3) You must be very bothered by Rav Shach’s very novel pieces in Sefer Avi Ezri.
4) The Rebbe’s encyclopedic knowledge, near photographic memory, and lighting-fast wit, enabled him to validate himself with sources in seconds. If this was your main issue and you discovered the secret concept of learning to better understand, and had you gone to The Rebbe and asked for sources – he would have given you a dozen sources for every point in one minute.
I am very against inferring real world abilities, from virtual interactions. But it does seem like you really never learn anything.
