UJM:
In other communities, if a woman doesn’t keep tznius we just label her as Modern Orthodox, and voila, our community no longer has a tznius issue because she isn’t “part of our community” anymore. I personally am totally fine with this system, but Chabad doesn’t seem to do it. They seem to have this “us against the world” sense of solidarity where they never internally criticize, as you can see on this thread. The result ends up being that Chabad women who are by anyone’s estimation Modern or Conservadox get to go around calling themselves “chasidish” and nobody in their own community calls them out on it. Maybe they do privately among themselves.
My point is, the Ashkenazi world has created a clear cut divide between women to care about tznius and those who don’t thanks to contemporary sectarian labels. If you included the MO as part of our tzibbur the same way you include Chabad-Lite as part of Chabad, then I’m not sure our stats would be any better on this issue.
