Sensitivity training needed!

My daughter Jessica is 17 years old and a senior at Hillwood High School.  She came home on Friday to tell me how the assistant principal (emphasis on the first three letters of that title) came up to her in the hallway and proceeded to talk to her about her “looking like she had an eating disorder, or diabetes, or a thyroid problem” which really upset her.  My family and my husband’s family both have very close relatives that were extremely thin when they were younger.  She can (and does) eat everything in sight and still does not gain weight, and she is 5’9 which adds to the problem.  She is very concious of this, but she is also a very healthy eater, and only drinks water most of the time.  After the lady coach and guidance counselor calmed her down in the office, she came out and he again had to reiterate the fact that he thought she needed to go to a doctor and find out what was wrong with her…he has also been known to walk by her at lunch to look at her plate and see what she is eating. Several times. Last year he walked up to her in a class and in passing she made the comment that it was cold…he told her she just needed to eat something!   I complained to the head principal, who was very condescending but promised to talk to the “assistant ” about it.  I also reported this to the MNPS because I want this person to be held accountable for this action.  If he had walked up to an overweight child and said to them “Wow you are just to fat! You must have a thyroid problem, or an eating disorder or diabetes, you need to go to a doctor” there would be huge consequences, and I feel that he should be held accountable for treating my daughter this way.  This is from the same person who accused my son of being on drugs when he had never even met him before.  This guy is a complete train wreck and does not need to be in a position of influence in this or any other school system.  I realize by going tro the lengths that I have I could put my children at risk of his retaliation at school, but if this does happen then their daddy Jeff is my tag team…and they think I’m a pain? I received a call from the really nice lady at MNPS and she has promised me that he will not say anything to Jess again, and was very understanding.  I told her that I think this person needs to have sensitivity training…cause he is very rude and apparently doesn’t think anything about it!  How did he get to be in a position of power over kids?
