As long as a child's parents are American citizens, either NBC or Naturalized, at the time of birth and born on American soil, that child is a NBC! It's what our government states, it's what our Constitution states, both Houses of Congress have NOT passed any laws to change this, and it is what it is!

The written Constitution floats in a vast and deep and, crucially, invisible ocean of ideas, propositions, recovered memories, and imagined experiences
The Invisible Constitution is not simply a mask for imposing a particular ideology on the Constitution, which is what people sometimes think. What I am hoping is that people will come to see that were all engaged in the same game and that the political reality of the Constitution, which is not confined to the written text, is an equal-opportunity reality.
