Rachel Dolezal: 'No biological proof' she has white parents

10. I've been reading about the one drop rule recently, reminds me of something else in history

Who is black ? One nations definition
The One-Drop Rule Defined

To be considered black in the United States not even half of one's ancestry must be African black. But will one-fourth do, or one-eighth, or less? The nation's answer to the question 'Who is black?" has long been that a black is any person with any known African black ancestry. This definition reflects the long experience with slavery and later with Jim Crow segregation. In the South it became known as the "one-drop rule,'' meaning that a single drop of "black blood" makes a person a black. It is also known as the "one black ancestor rule," some courts have called it the "traceable amount rule," and anthropologists call it the "hypo-descent rule," meaning that racially mixed persons are assigned the status of the subordinate group. This definition emerged from the American South to become the nation's definition, generally accepted by whites and blacks. Blacks had no other choice. As we shall see, this American cultural definition of blacks is taken for granted as readily by judges, affirmative action officers, and black protesters as it is by Ku Klux Klansmen.

Let us not he confused by terminology. At present the usual statement of the one-drop rule is in terms of "black blood" or black ancestry, while not so long ago it referred to "Negro blood" or ancestry. The term "black" rapidly replaced "Negro" in general usage in the United States as the black power movement peaked at the end of the 1960s, but the black and Negro populations are the same. The term "black" is used in this book for persons with any black African lineage, not just for unmixed members of populations from sub-Saharan Africa. The term "Negro," which is used in certain historical contexts, means the same thing. Terms such as "African black," "unmixed Negro," and "all black" are used here to refer to unmixed blacks descended from African populations.

Uniqueness Of The One-Drop Rule

Not only does the one-drop rule apply to no other group than American blacks, but apparently the rule is unique in that it is found only in the United States and not in any other nation in the world. In fact, definitions of who is black vary quite sharply from country to country, and for this reason people in other countries often express consternation about our definition. James Baldwin relates a revealing incident that occurred in 1956 at the Conference of Negro-African Writers and Artists held in Paris. The head of the delegation of writers and artists from the United States was John Davis. The French chairperson introduced Davis and then asked him why he considered himself Negro, since he certainly did not look like one. Baldwin wrote, "He is a Negro, of course, from the remarkable legal point of view which obtains in the United States, but more importantly, as he tried to make clear to his interlocutor, he was a Negro by choice and by depth of involvement--by experience, in fact."

The phenomenon known as "passing as white" is difficult to explain in other countries or to foreign students. Typical questions are: "Shouldn't Americans say that a person who is passing as white is white, or nearly all white, and has previously been passing as black?" or "To be consistent, shouldn't you say that someone who is one-eighth white is passing as black?" or "Why is there so much concern, since the so-called blacks who pass take so little negroid ancestry with them?" Those who ask such questions need to realize that "passing" is much more a social phenomenon than a biological one, reflecting the nation's unique definition of what makes a person black. The concept of "passing" rests on the one-drop rule and on folk beliefs about race and miscegenation, not on biological or historical fact.
