Call it "pc" if you like, but that's exactly how we say it to our kids. Our children can trace their ancestry back to both Africa and Europe. We just tell them they're Americans. Their ancestors came from those continents. They were born here.
Of course, the eldest, 11, has come to view himself as black, anyway. Labeling oneself as black or white is practically unavoidable because those are the labels everyone else wears and puts on him.
"Black" and "white" I can understand, but it's "white" and "African American" in the article.
