This 1969 data explains why I have largely given up being "socially correct." In my non-racist childhood upbringing, I don't even recall our darker skinned friends being referred to as anything related to skin tone. But, I have always wondered who came up with the trend-of-the-day, socially "correct" terminology. It has changed so often over my lifetime for several things, it just seems rather silly to me. I had a "mongoloid" brother who became a victim of "Down's Syndrome." My son with several behavioral traits (disabilities) received five different labels (diagnosis) in his school years, all trying to describe the same thing - but, at different points in time, being the "socially correct" terminology. Give me a break!
Back to the topic at hand, I think "American" is label enough, whether you were born here or chose to become one of us. We are the "melting pot" of the world, after all.
