Devorah K, I think Shindy’s way of non-judgementally reminding the women about kasherus is very good. If you are going to start heaping tochacha upon tochacha, then you will lose them about everything. Think about when you were in school and a teacher would start a lecture like that. The average student just turned off. Pick your battles or you will lose everything.
Teenager, I think you are great that you want to help other kids but just because somethng is very bad, doesn’t mean you should ingnor the bad things.
