Here are several articles explaining[0,2] how that one phrase has been co-opted and misinterpreted to mean exactly the opposite of what MLK intended. If you're curious, Google can reveal many other discussions on this topic.
Okay, first citation [0]
Joanne St. Lewis is a law professor at the University of Ottawa. Her teaching, research and legal work focus on social justice issues.
She cites no references to support her opinions.
Second citation [1]
Assistant Professor of Law, University of Alabama School of Law. B.A. 1980, Wilberforce University; J.D. 1984, University of Pennsylvania Law School.
Again, it's all his opinion with some supporting examples, but no citations.
Third citation [2]
Bev-Freda Jackson
Adjunct Professorial Lecturer, American University School of Public Affairs
Jackson's article is better, but still includes logical fallacies.
"By recasting anti-racism as the new racism, conservative GOP leaders such as Grassley and U.S. Sen. Ted Cruz, a Republican from Texas, use King’s words that advocated for a colorblind society as a critical part of their national messaging to advance legislation that bans the teachings of so-called divisive concepts." She doesn't explain what the problem is here, why what they're doing is wrong, or how and why anti-racism is not actually racism.
Citing Dr. King's children opens the door to analysis of their character, and their politics.
Thank you though, I now understand that recent academic activists have attempted to diminish Dr. King's message using double-speak to push their racist agenda. They should be ashamed of themselves.
None of the above applies in any way to the TED video (which I watched and enjoyed). Coleman Hughes does not disparage Dr. King or his message, and probably doesn't care much for anti-racist rhetoric.
