One is clearly a stringent practice and the other sounds kind of oppressive.
I don’t know a single high school kid that would make that distinction, and the teachers are betting on it. If not, you can throw out all Chassidus, none of which is Halacha (and much is against, such as Z’manim).
Besides, can you blame her for thinking that all Chassidus is like Satmer and has the same rules?
Someone is defensive. Are you also a Chassidish woman? See my post to MSSeeker. Don’t feel the need to justify yourself.
