We need high resolution, objective data to do proper discrimination. I'm on the order of efefef, but I'll have to go back and get the real results as my memory of doing this some years ago has faded.
In fact, people are not as easy to categorize by skin color as by eye color. Most Americans have very mixed ancestry. I call myself a Heintz 57 American, and one day I was having a long complicated conversation with a relative of a black friend who had died. When I said that I could see that she was part Indian from her features she really warmed to me looking at her and seeing an individual.
The rigid black/white divide is something that has been exaggerated and made worse by the civil rights industry. Blacks, whites, and Indians have been living together for 500 years with all kinds of different interactions. In this year of the halfrican american, ask where he/she fits these stereotypes. And note also that the lady from small town Iowa did not know whereof she spoke, as there were no blacks in her town.
