Menachem,
It’s cute the way Lubavitchers twist themselves into pretzels justifying their long-departed Rebbe as Mashiach, then complain that’s all the Snags want to talk about. If it’s really not such a big deal, please answer the following yes-or-no question, which you have refused to do so far:
Do you consider it within the realm of possibility that someone besides any of the seven Lubavitcher Rebbeim, zt”l will be Mashiach?
