Qwert, i have to take issue with some other things which you’re saying, which i believe to be in error. The “chamushim” which chazal darshen as being 1/5(aside from the pshat of “armed”) is not universally agreed upon. There were different midrashim. How that will work when moshiach comes isn’t simple – we need to go back to that medrash and figure out why in fact so many were not zocheh to be redeemed.. it’s because they didn’t want it; they were comfortable the way they were. So if klal yisroel is the same way, the same thing will happen. if more jews are metzapej l’yeshuah, less will be left behind.
Re, chasidim thinking that their rebbe is “moshe” – this has a source, sort of. The zohar says that every gadol is ispashtusa demoshe in every generation; the continuation, the spiritual powers Moshe had were passed down from generation to generation. Chazal call each other Moshe when they say a sharp thing, etc…so it’s not as if chabad invented the idea. Chabad did, however, invent the idea that only THEIR rebbe is like that and they extended it to silly things like thinking that their rebbe was bigger than the rambam because the latter didn’t have access to chasidus.
