The first African slaves arrived in America in 1619. That’s 399 years ago. If we count twenty-five years as a generation, that’s 16 generations.

Now, lets look at you and your ancestors. Chances are, they haven’t been in America for 16 generations. In fact, this being the internet, chances are you aren’t even in America, so let me explain.

Here in America, whether you are white or black is a big deal.

If you are from India, or Indonesia, or the Philippines, or just about any place else in the world, you are likely to have your own racial and ethnic issues. Your tangle may be different from our tangle, but it’s probably just as tangled.

Being black or white in America isn’t as big a deal as when I was a kid, but it’s still big. And that is true even though there is probably no American black who is actually, fully, and truly black. Don’t take my word for it. Here is what Langston Hughes, negro poet,  said in his autobiography:

You see, unfortunately, I am not black. There are lots of different kinds of blood in our family. 

Being white in America is a big deal too, in the other direction. And that is true even though very few whites are actually, fully, and truly white. Don’t take my word for it. In 1895, speaking against defining whiteness in the new South Carolina constitution, Congressman George Tillman said:

It is a scientific fact that there is not one full-blooded Caucasian on the floor of this convention. Every member has in him a certain mixture of… colored blood…It would be a cruel injustice and the source of endless litigation, of scandal, horror, feud, and bloodshed to undertake to annul or forbid marriage for a remote, perhaps obsolete trace of Negro blood.

A generation later, several southern states did define race, declaring that one black ancestor, however distant, was enough to turn a white man black. It was a sad day for those perceived to be black, and a bad day for truth.

Back to your ancestors. You had two parents (we’re speaking biologically here) and they had four parents and they had eight parents . . .; up the line 16 generations, that’s just under 33,000 ancestors sending their DNA down the line.

Can that be right? Let’s look. The first generation is you, alone, and for the rest we will need a chart.

               9                  256
               10                512
               11                1024
               12                2048
               13                4096
               14                8192
               15                16384
               16                32768

You have 32,768 great . . . great grand parents. If you are a “white” person in America, what are the chances that not one of them was out of Africa?

If you are just of the plane from rural Norway with ancestors going back unbroken into antiquity, as soon as you have a child with an American who has been here, that child’s number becomes 16384. You can run scenarios to lower the number, but it will never drop below BIG.

All right, let’s say you are a member of the Aryan Nation, and your father and his father were Klansmen all the way back to Appomattox Courthouse. You only marry white girls, and only natural blondes at that. What are the chances that her thirteenth great grandmother wasn’t partly black and passing for white?

You don’t think so? Your ancestors knew better back in the 1800s.

Let’s go at this from the other direction. Suppose one black woman was made pregnant by her master in the first generation. How many of her descendants would carry at least a trace of African DNA? All of them. How many would that be?

Historically, women bore many children, and many of them died while young. Let’s say that the average woman had four children who lived long enough to have children of their own. That original black woman would have one billion, seventy three million, seven hundred forty one thousand, eight hundred twenty four descendants.

You don’t believe me? Get out your calculator. No, better make it a spreadsheet. You don’t think I did that math with pencil and paper, do you?

What are the chances than none of those children passed for white, and begat a line of offspring who are convinced that they are actually, fully, and truly white?

Let me put it another way —

Donald Trump is partly black. David Duke is partly black. Steve Bannon is partly black. You’re partly black. I’m partly black.

And my relatives just disowned me. That’s mighty white of them!
