I walkes around Crown heights when i was young, about 15 years ago, shmoozing with tens and tens of people, walking into dozens of random sukkahs, and EVERY SINGLE PERSON TOLD ME THIS!!! Stop with your revisionist history.
Even if that's true, and it very well might be, if you're not educated enough on the topic I think you may be better off listening than ranting. You're trying to convince a bunch of Chabadniks of what they believe when they are sitting here telling you the opposite.
I've met plenty of people who also were over obsessed with the Rebbe and also believed he was Moshiach. And I still know enough to know that that is not the basis of Chabad. And there are PLENTY who don't think like that at all.
It seems like you're so set on believing what you want to believe so you can hold on to your "disgust" and feelings toward Chabad etc.
I won't deny there are Chabad wackos but why focus on them?
