This UK school that wishes to remain anonymous. Letter from the head teacher.
"Dear Daniel and Sarah,
we noticed that Laura has a Wonder Woman lunchbox that features a super hero image. In keeping with the dress code of the school, we must ask that she not bring this to school. The dress code we have established requests that the children not bring violent images into the building in any fashion — on their clothing (including shoes and socks), backpacks and lunchboxes. We have defined "violent characters" as those who solve problems using violence. Super heroes certainly fall into that category. Asian children are still allowed images of the Prophet Muhammad, as this is considered a religious icon of peace. Please refer to the dress code section of the School Handbook. Your cooperation with our dress code will be appreciated."
