You have done an excellent job responding to a point almost entirely unrelated to the one you quoted.
He was talking about white supremacy, not slavery. And the phrase "all-American concept" does not mean that America invented it. He means that it's intrinsic, pervasive.
Which is pretty obviously true. America was white supremacist from the get-go. If not, we wouldn't have needed the 15th amendment, which came circa a century late. We wouldn't have needed 8 different civil rights acts (so far). The notion of whiteness is something America helped create and is continually redefining so as to help maintain white supremacy.
