You have improved a little each time. The first book was published in the 1800s and was not actually a textbook. The second book was published in the 1920s, the third book was published in the 1930s. I said that I had been unable to find any of the civics text books from when I went to school. You said that there were “truckloads” of them on Amazon. You haven't found even one textbook from the 1950s, 60s or early 1970s. I took you at your word and said that you must be much better at searching Amazon than I am. Actually the examples you have provided to back up your claim of “truckloads” are pretty pathetic. In fact if that is the best you can do I would say that your claim is an embarrassing exaggeration. I was taught in school that a natural born citizen was a person born in this country with two citizen parents. A lot of others remember being taught the same thing. Why can't you find some textbooks from the time period that we went to school and prove us all wrong?
