Quoted here:
[I]magine a 1960s civil rights movement led not by Martin Luther King Jr. and John Lewis, but by Al Sharpton and Jeremiah Wright. King did not simply speak to the passions of his followers but to the consciences of his detractors and to the consciences of those on the sidelines, overhearing it all. Behind that was a coherent set of ideas, grounded in the Bible and the Declaration of Independence.
