They haven’t pushed back because the differences between tzfas and the rest isn’t very large. They mostly pray to, and ascribe godly characteristics to him. They all believe in atzmus ideology because the rebbe said so. There’s a limit to how much they can disagree, while I will admit that many do not ascribe actual divinity, or they are not in the “inner circle” (i.e., they’re BTs, gerim, or came from somewhere else) and are unaware of these ideas.
Nomesorah; at this point you’ve reduced your argument to “how much is it” – a little, a whisper, or a standing ovation – what’s the difference? There’s an alien monstrosity posing as yiddishkeit, no matter how enthused the reciters of that garbage are or not.
For the record, in the states it seems they say it lowly to themselves, which of course is fine in your world where you believe that we shouldn’t care what people believe as long as they wear fabric on their head, put leather boxes on their arms, and eat food with funny symbols on it.
