When we contemplated homeschooling, we had feedback along the lines of "What about socialization?"
My frequent thought (occasionally voiced): "Have you read Lord of the Flies"

Play and playgrounds at school have a life of their own and they are handed from class to class over time as they morph and take on a life on their own that teachers have little direct control over.

It seems so complex when the correct, "taught" way to "user your voice" particularly when it is quite an adult voice reads even nerdier to other kids.

Successfully implemented, I think your daughter's approach can be healthy, first off: it removes the power from the people doing the teasing, secondly: it allows her to have control over the acceptable bounds by providing negative feedback when her chosen line is crossed, and if you are going to march to your own drummer, make sure he beats that drum loudly. Not everybody is comfortable with self-deprecating humor and other ways of retaking control without conflict or want their kids to be that way.

In an ideal world...?
