REVISIONIST CONSTITUTIONAL HISTORY:

The myth that blacks were categorically barred from citizenship and political participation at the time of the Founding was popularized by defenders of slavery in the nineteenth century, most notably Chief Justice Roger Taney in his majority opinion in Dred Scott; Taney advanced this idea to justify his claim that, at the time of the Founding and under the Constitution, blacks “had no rights which the white man was bound to respect.” In the twentieth century, ironically, Taney’s argument was recycled by some left of center critics of the original Constitution. The disreputable proslavery origin of this theory does not prove it wrong. But the historical evidence does.

Funny about all the proslavery stuff — like the “one-drop” rule — that has been adopted by people on the left.
