Parents of girl should SUE this school till it bleeds.
That is of course how the culture war needs to be fought. In the courts. Sue every time. There should also be a class action suit against the school, and those responsible for the policy.
Suing school districts only punishes the taxpayers. If the idiots that approved this policy are unpunished, what has been gained?
There should be firings and pension revocations instead. Then you'd see some changes.
