“There are many things to criticize Chabad about, but tznius is an unfair one, especially in this dor.”
That’s what I said even when I was in the thick on the fight on this thread. It’s usually a throwing stones in a glass house scenario when people bring it up. Any tznius problem in Chabad is nowhere near as bad as in the MO or Open Orthodoxy.
I will say for RSo, however, that he has been upfront that he is speaking from a Chassidish point of view concerning this. I think the tznius problems in the non-Chassidish community are irrelevant to him. His gripe is that the Chassidish world has always enjoyed a status of having better tznius, so for one high-visibility group to throw that into question by claiming to be the authority on what it means to be Chassidish would be frustrating.
