The majority of idiotic things like this in schools is because enough parents complained and probably threatened a lawsuit. Sometimes it's easier to appease the parents than fighting. Have you ever worked in a school? The sheer amount of threats and complaints are mind-boggling. If somebody is worried about losing their job, it's pretty simple to cave to a request like this. Yep. I see it on these boards all the time. Posters are immediately encouraged to go to the superintendent, sign petitions, call for the firing of the teacher/principal etc.
