I’m not sure about that, but Taylor Branch uses that “wink and nod” concept to describe how Ralph Abernathy, Andrew Young and other associates of Dr. King reacted to his sex habit.
OK, a bad joke. Both would be cleansed saints at that point and no nodding or winking would actually happen. But King and Solomon could well say to each other “I know, that’s what happened when we thought with the wrong head.”
