“because they will REJECT the Melech HaMashiach”
I have a real problem with this type of statement. Similar things have been said before, like Moshiach will be rejected by some because he wears a srugi, by others because he wears a shtreimel, etc. It’s a backwards attempt to call for achdus, but the root of it is denigration, either of specific groups of Jews or all Jews. What you wrote doesn’t even have the veneer of calling for achdus. When Moshiach comes, it will be like the shevatim when Yosef declared, ??? ???? ???? ??? ?? and everything that had happened fell into place in a second and they were too shocked to speak. We will understand in a flash, and the beis hamikdash will be rebuilt and we will all return to Eretz Yisroel. It won’t be like some guy who sponsors a big kiddush, gives a middling drash by the Galil, throws some tables over in the courtyard, then gets himself executed by the Romans and his followers have to try for the next 2000 years to convince us using weird distortions of pesukim. It will be so comfortingly clear it’s described in the nevi’im as a baby nursing his mother.
