Ther is a passuk that says “ho’chaich tocheach es amisecha v’lo sisah alov chait”: “rebuke you shall rebuke my people, and there will not be a sin on you”.
Not really related to the direct conversation but the second half should be translated, “and you shall not bear a sin because of him”. As in, if a person will hurt someone by giving rebuke, do not give rebuke at all! May be why some people are convinced “rebbetzins” should go over to people in short skirts and give them as much mussar as possible.
