It is like getting a slap in the face when you discover people have said unpleasant things behind your back. It is even harder when you know that you are not in a position to confront the person concerned. Goodness knows what people have been saying about us I'm sure I have helped while away many hours at the hall whilst people tutted over me.
Ignorant people do not gain credibility by saying stupid things. Unfortunately JWs are taught to be judgemental and harsh particularly to people who are outside the group. it is their nature. Remember they are the happiest people and nothing makes them happier than bad mouthing others.
