Avram,
There is a particular minority section who annoyingly(to put it lightly) proclaims it and have more right leaning views. Most dont like them. But even the ones that dont like them think the rebbe is moshiach.
“And my ancestors are the villains of their stories” you clearly have a lot more issues here with lubavitch than the messianism. Coincidently everybody who posts about this issue always has another 50 problems with something chabad does that makes them intolerable. Im not saying its sinas chinam but it definitely isnt a simple pure and kind question of sources either
