Dr. King, it seemed, carried a low-temperature but constant rage within. He endured a lot: death threats, bomb blasts, a stabbing, incarceration. But most of all he endured the strain of knowing his dignity and humanity mattered, even when society and its laws said they didn’t. He bore the prophet’s burden of knowing it was his responsibility to demand a better reality for his people, a better way for all of America. Yet, America—especially the America of Alabama and Georgia and Mississippi—was not ready to listen. This had to be maddening.
