A personal story (avoiding names and details.)

Mrs. P. and I got burned by a person like this. We had never really trusted her, but we had to associate with her. What she did to my wife was out of the blue, horridly timed, and just awful. Wrecked our lives and relationships with others for years. We tried to warn others but they'd roll their eyes or tell us we were the crazy ones. When she found out we were warning people, that just upped her smear campaign. Eventually, she wound up fucking with the people we had warned. Some of them now, when the situation comes up in conversation, refuse to talk about it or even mention her name. She gets referred to as "She that we name not."

My point was that this is what make people like "He that I name not" so dangerous is that people either don't see the pathology, or they ignore it, or they try to ride it for their own gain, or they like it. Because maybe they have the same problem.
