Reb,
“Aren’t they the ones that “many gedolim” (invisible ones like my invisible friends) consider them Ovdei Avoda Zara?! ”
You are probably confusing me with “Lernt” but regardless, the ones having an issue with Chabad are with the most recent Meshichists, absolutely nothing with the ones mentioned. In any case, you did not respond to the point made, regarding the so-called dress code “mesorah’
And btw, that sefer mentioned is clearly one with an agenda, aa some have pointed, so the “shitos” are probably just the way he understood it and should be taken with a grain of salt.
One clear psak of the Chasam Sofer probably שקול נגד כולם…
