I understand what you are saying. I think most of us are use to seeing all of a person's "problems" die with them and all of their good qualities celebrated. Even Richard Nixon received this treatment after his death. I think one of the problems is that we try to compare how Janet should honor her brother based on how youy or I would act. One very telling statement she made to Oprah is that she had lost Michael as a brother around the time of Thriller. I know there are some who will interpret her words based on what they believe she meant or what they want her to mean; however, I will take Janet at her word. She chose her words deliberately. She didn't say they lost closeness or couldn't spend as much time together, she said she lost him as a brother. If he ceased being like a brother, emotionally, what was he to her at point? Maybe this could explain why she isn't responding like many expect a sister to do. Also, as Michael's body lay in thee freezer at FL for weeks, a family friend/relative gave an interview to a paper and the person seemed livid. He/she said that the Jackson's were fighting over where to bury him, etc... and they treated Michael more like a celebrity than a brother. I will try to find this article when I get home because it can explain a lot about what we are seeing now.
As far as Janet's book is concerned, she has every right to tell her story and I think most mature people would agree that derogatory name calling is wrong. I don't know if she discusses it in her book and it has been ignored by the media but there has been some big issues abscent from her interviews. Namely, the role of the parents, teasing/name-calling being accepted in her family. Also, when Michael knew better, he apologized. Noone can un-say something so the best Janet could get was an apology. Finally, self-esteem is just that, self-esteem. No one can take your self esteem, you give it away. Hopefully she discovers what it is within her to internalize negativity and take ownership of it. That's not her brothers fault, that's all her own.
