CS – please adress two points:
1) How the Lubavicher Rebbe a=can still be Moshiach even though he is presently dead, when the Rambam says otherwise.
2) Even assuming the Halacha is not like the Rambam, why is the Rebbe the greatest of all possible dead candidates
3) Why there is a chabad obsession to identify their dead Rebbe as Moshiach even though it contradicts all the evidence, no other Jewish group has this obsession, and it makes a chillul Hashem and Chillul Lubiavich for all onlookers, and there is nothing to be gained by it other than perhaps fulfilling a psychological need. It certainly doesn’t bring Moshiach closer.
