One way to change worldview perceptions is to keep people ignorant. The public schools have done a great job in shifting worldview thinking from theism to humanism right under the noses of parents who extol the virtues of America’s government education system. Consider how textbooks handle the subject of religion in the founding of America. One elementary school social studies book has thirty pages of material "on the Pilgrims," Paul Vitz writes, "including the first Thanksgiving. But there is not one word (or image) that referred to religion as even a part of the Pilgrims’" life.
