Now, tell me how you're going to teach the history of Jefferson, and cut out all those quotes and cut out all these facts, and cut out the key line of the Declaration of Independence: We are endowed by our Creator. I mean you have to have a conscious deliberate censorship of America, which is what the left and the courts and the classrooms has had for 40 years.
