Visitor: While I accept your viewpoint, I don't necessarily agree with it. If he is just soliciting feedback from parents, teachers or students at the school then his survey is perfectly acceptable. By your admission (and if you are not a teacher), then you don't fit into these categories. That does not mean to say that your opinion is not important. It just means that your opinion does not fit into the metric the survey is asking for. There is nothing offensive about asking such a question. Your opinion is valid elsewhere, just not in this survey.
I agree with you: any civilised society has to put resources into making teaching excellent. This is the only way for society to grow and create, amongst other things, tolerance
