I have not read the entire tread, but I associate bullying with Pluto. Pluto represents our shadows, the unwanted within us that we hide away. Feelings of being humiliated, believing that you have less worth than others, feeling powerless, feelings of shame, feeling that we can´t get what we need etc.
Our shadow will not disappear because we ignore it. If we are people who direct our shadows inwardly, we will attract people who mirror the shadow and treat usthe way we think we (often unconsciously) think that we
deserve to be treated. If we are the type of people who direct our shadows outwardly, we will make other people feel the suffering that is within our shadow. People who do this seldom sees what they are doing. They believe that the victim triggered them or that the victim was "asking for it" and therefore it is the victims fault. That way they justify being psychologically, physically or sexually abusive.
