Peggy Orenstein has written a fascinating little essay in today's Times Magazine. It is called "Mixed Messenger," and in some way it is about Barack Obama. It is also about Orenstein's four-year old daughter and her unborn grandchildren. And will they be Jewish? And actually about the United States or what the American population of tomorrow will look like. Or think of itself as. How will we calibrate or identify identity? How will we get statistics on anything? Yes, ours' is the second big mixed-race country. The other being Brazil. Orenstein introduces us to the word "Hapa." And to the demographics of Hawaii. which is our biggest mixed-race state.She also tells us about Tiger Woods and why he is still black.And much more.
