It isn’t your relationship with her I’d worry about, by the way; it’s the possibility that if she feels insulted, she’ll unconsciously take it out on your kid.

This is always my first consideration when dealing with my kids' teachers. I have liked and appreciated their teachers, but when I have felt frustrated with one of them, I've forced myself to wait and engage calmly and kindly, and only when absolutely necessary, because I want to avoid intentional or subconscious retribution against my child.

I hesitate to say what I would do in LW's place. I'm not a woman, so I don't experience the sexist expectations LW does. I wouldn't be in this situation. But I think for most parents, the potential ramifications on the child would factor into the decision.
