TS, I wasn’t saying you should answer for other chasidim. I’m saying that it’s typical myopia where whatever chabad says is the only way things are – if chabad holds something isn’t tznius, then it’s not tznius, regardless of how many other groups of legitimate jews do it (or is no one else legitimate?….)
It would be like me telling a sefardi that I don’t warm up food on hotplates on shabbos because it’s chilul shabbos, while he does and is a mechalel shabbos. No – the way I tell him is that Ashkenazim hold that we’re not allowed to heat up food this way, because we hold that it’s nesinah lechatchila, but we respect other minhagim which permit it.
To be clear, satmar has higher standards of tznius in dress than chabad by a wide margin. They also separate genders far more fastidiously, and keep shmiras aynayim better because they don’t go out to the outside world.
In my own experiences, there are certain trends that go on in crown heights which are acceptable, and not treated with revulsion as they would be elsewhere. The details of this aren’t tznius to post online, but hamyavin yovin.
The amount of violations would be less if there were clear community guidelines as there are in boro park and Williamsburg (moreso in the latter). Every community has problems, but at some point, if not checked, they will spread, and in an effort to be mekarev people with little yiras shomayim, you will cause a community wide abandonment of tznius and other mitzvos.
