peselmalka, I think you are way off because if you want to help someone make changes that is not the way to do it. That is probably why she is at the madreigah she is at right now because of people who are pushing and shoving at her, and not because people are showing her the right derech in the right way as others are trying to point out here.
You can’t change other people only yourself and you can’t control others only yourself. So how do you bring about change in other people? In order to bring about change in other people, you can only change yourself and watch how others respond to your change.
Obviously yelling at movingmountains, will not encourage her or anyone else to lengthen their skirts or buy longer skirts in the future. Threatening her with gehenom or wrath from Hashem will not either. How do you know what she is going through and how far she has come that Hashem will judge her harshly? You don’t know that at all. You don’t know where Hashem’s compassion and rachmonos begins and ends so where she is concerned. Hashem will judge each one of us individually according to our own mitzvos and aveiros and YOU can’t tell anyone how Hashem will weigh them, and which will outweigh the other. So please put your pitchfork down and pick up a harp so you can play and sing a different tune.
