That's seven generations. Five "greats" does not mean five generations. A grandparent is two generations. Thus, add it to the five greats. Seven generations ago. Negro IQ. And even if seven generations ago they weren't slaves, which they likely were since that's quite long ago, the point still stands. Whichever is the number of generations, you're only being the social burden you are to the world because once upon a time your ancestors had property value. Now you can't be legally bought, so you're completely worthless.
