I am sure that you will find that in today's world santa's antecedents would be classified as economic migrants. Just like that nasty lot south of your border, who will soon, given trends in birth-rate, be in a majority; certainly in California. It would be rather neat to see the demographic scales reset to pre-19th century values. If the racists allow it, this might even happen elsewhere, e.g., Arizona, Texas, Florida etc.
Of course if santa was really serious about thinking about, let alone acknowledging, the sad story of American imperialism he would not take such umbrage at my post referring to Cuba, the Philippines and the Native Americans. Me thinks that the doctrine of Manifest Destiny ever so slightly lives on in this particular history teacher. A very comforting and self-reassuring position for him to hold; let’s hope his charges are more open-minded.
