Author Maya Angelou first brought attention to the issue. The original quote was, "Yes, if you want to say that I was a drum major, say that I was a drum major for justice. Say that I was a drum major for peace. I was a drum major for righteousness." On the monument, it’s paraphrased to read “I was a drum major for justice, peace and righteousness.”
Angelou said it makes Dr. King sound arrogant.
The entire quote didn’t fit on the monument.
