A minhag that goes against halachah is a minhag shtus, and has no validity
DaMoshe and I agree that you either mock all these minhagim or not. You can’t choose to only mock Chabad.
I personally think these minhagim (Sukkah, Shemini Atzeres, Menorah) are valid (though I keep the two that I was taught), while DaMoshe thinks they’re all invalid.
Maybe the next time a Chabadnik asks me if I put on tefillin, I’ll say, “It’s not my minhag to do that, and you know all about following minhagim that go against halachah!”
Hold it, it’s not just Chabad that you’re trying to mock!
On the contrary, you happen to practice the Chabad minhag (albeit for other reasons)!
You also mock all the non-Chabad chassidim who have a minhag of eating outside the Sukkah on Shemini Atzeres, and all the Jews who have a minhag of davka lighting menorah indoors.
How come your post ended specifically about Chabad? How does it keep coming back to that?
