I always thought that school was where kids went to learn about all sorts of things, and were taught to sift through all that they studied and make informed decisions. No wonder our public school system is a joke.
While social conservatism has an important place in our society, we do our children a disservice by pretending that is the only school of thought. Creationism should be taught alongside the theory of human evolution, all religions should be discussed, our nation's history should be taught as it was, even the ugly parts (especially the ugly parts, that way future generations might not have to repeat them...), capitalism and communism should be taught, heroes and villains should be called what they are. Sad to see a few individuals being so narrow minded as to want to exclude knowledge from our youth.
Academia is liberally skewed in its upper echelons (college and onward) no doubt, but K-12 should be the time where all points of view are discussed, without bias, so that kids grow up knowing there are others that think differently in the world. Makes for better adults.
