"The question is, how do you stop the power elite from doing as much damage to you as possible? That comes through movements. It's not our job to take power. You could argue that the most powerful political figure in April of 1968 was Martin Luther King. And we know Johnson was terrified of him. We have to accept that all of the true correctives to American democracy came through these movements that never achieved formal political power and yet frightened the political establishment enough to respond."
