Avira,
I pashut don’t have time for all of these and they are only getting longer and longer. I’ll have to keep things brief.
1. Ruzhiner quote from a Sefer called kerem beis yisroel. It’s also published in sadigura publications searchable on otzar. The book itself is hard to find but I have a picture of it if needed in email.
2. Is moshiach judged for the matzav of the world or his own actions influence? If the former then he gets just as much credit for the fall of communism as he does whatever intermarriage rates ur describing. If his direct actions then he shouldn’t get blame or credit for either. Be consistent. In the vast majority of cases secular peoples Judaism is better served when involved with lubavitch.
3. I think ur choosing random metrics to judge Moshiachs success and I just don’t agree with the value system ur producing. if an intermarried guy became part of a regular minyan when before he wasn’t ur gonna say that’s a failure, even tho he is now doing more net mitzvos? I don’t see how intermarriage ruins the other things the guy could be doing to increase his Judaism. More so a woman who is still having Jewish kids.
4. Ur tefillin arguments are old enough already. R hutner was chavrusas with the rebbe. He said many great things about him. See the rebbes back and forth with rav hutner over tefillin here https://anash. org/exploring-the-correspondence-between-rav-hutner-and-the-rebbe/
5. I’ll disagree with ur understanding of Russian Jewry. In general I think ur severely underestimating the rebbes role in a variety of affairs, his genius and respect amongst various torah personalities. When someone says the rebbe is maybe a gadol kinda, I already know their understanding of the rebbe is severely off base. But that’s just my opinion ur likely to say the opposite in response. Nu Nu. Anyways the main point is there are sources for moshiaxh coming from the dead. This specific way of his coming is not the threads purpose and it’s much too long to rebut at length here back and forth. Let’s acknowledge one thing at a time. That the Ruzhiner could come back as moshiach is already a chiddush to ur mind and likely other readers. Let’s sit with that for a few weeks before piling on.
