Gee, I hate to tell most of you this simple secret, but most Mexican people are classified as Caucasions.
By definition, caucasions are "white people".
They were predicting that same kind of bull manure in the very early 1900's, with the massive influx of Italians, Spaniards, Greeks, etc. But guess what? In about 2 generations, all of those "dark foreigners" were just as white as the Anglo-Saxons.
