“Saying that we’re Kofrim over this [davening late] is another. And getting insulted when we argue back is surprising.”
I don’t think I’ve seem or heard anyone assert that Chabad chassidim are kofrim due to zmanim. Certainly not me. That’s a straw man. The concerns are about the perceived deification of the Lubavitcher Rebbe ZT”L and changing the definition of Moshiach to fit him. And the idea that all Jews must accept these precepts or they are spiritually inferior.
