Hi, I hear you. I was also a bit taken aback when my reviewer did not seem to "get" our approach, which I had cultivated with great love and pride.
Then I realized that is not important. And not going to happen either.
fwiw, I dont think the teacher's comments were rude. In any case, from the teachers' point of view, s/he no doubt thought s/he was showing through her constructive feedback, that she cared, valued your child's writing, etc.
Still ... it hurts to have someone helping you when you didn't want help. However being a teacher, I guess they start from the premise that they are there to help. THey would give the same kind of comments to their students - to "help" them see what more / better they could do.
My reviewer told me that we shoudl work on lower case letters. I was not pleased. We will work on what we want, when we want, thank you. Later on though, I thought it was a useful suggestion. The key is not to take it personally, and just make the reviewer's work easier by having whatever you are supposed to have and showing appreciation for whatever advice they care to give. Later if you really think none of it was of any use, feel free to ignore it.
Same approach I use when dealing with pediatrician.
