"To those who are offended by the advocacy of religion in the classroom, it should be replied that Christians have just as much right to be offended by the teaching of various secular philosophies, which disavow our need for God. Christians ought to express this offense (including their offense at having to pay for this brainwashing with their taxes) more consistently and severely. Why should offensive teaching be limited to “religious” expression in some arbitrarily narrow sense? Of course, if a more evenhanded view of these matters were to prevail, we would all have to accept equally the burden of possibly being offended, or we should eliminate public education entirely. Education in which people of all convictions are enrolled, but in which no one is offended, is not worthy of the name."
