“And that’s aside from the fact that it’s halacha that you’re not allowed to doubt your Rebbe, and if you do youre doubting Hashem. Hilchos TT 5:5. ”
“Ahh, but אחר used to be עלישה בן אבוי׳ who we quote in פרקי אבות and went off the derech because he couldn’t keep the level he was on (פרגוד) and he taught ר מאיר before he went off”
Yes so what? Once he became a kofer and was acknowledged as such by everyone including himself, he was no longer a Rebbe, thus the halacha didn’t apply.”
It seems to chabadshluch You simply can’t go against a rebbe, unless the halacha doesn’t apply, eg. You’re a kofer thus not a rebbe. I hope I misunderstood her point
