I wonder if John C. Calhoun would cringe at a Soulja Boy contest happening in his college or if he would smile at the latest minstrel performance?

Hard to know.

In any case, he wouldn't be my first choice for a posthumous interview.

Hmm...

Besides biblical folk, I think I'd go with Walt, Martin, Howard Thurman, Malcolm, Frederick, Sojourner, CS Lewis, Ralph Ellison, and W.E.B.

Just off the top of my head.
