I don't doubt the memory just because there's nothing more dangerous than a teacher who can't recognize a Bible quote and who then attributes modern meaning to the speaker. MLK was a reverend so he obviously quoted the Bible a lot and the Bible can have some violent imagery.
But I can't see the man who said this advocating violence of any kind...
"Nonviolence is the answer to the crucial political and moral questions of our time: the need for man to overcome oppression and violence without resorting to oppression and violence. Man must evolve for all human conflict a method which rejects revenge, aggression and retaliation. The foundation of such a method is love."
The reality of the world is there's a place for all kinds. The thoughtful speaker needs the passionate militant because not everyone has an open mind. Think Martin Luther King and Malcolm X
Moreover, the world needs these type of people on all sides to make sure the truth gets heard. Even if Mr. Naggum wasn't speaking the truth his opinion helped keep minds open to his side of things.
Honestly, as annoyed as I get at times by people like him I can also see how it's a noble pursuit. As much as people say they don't care what other's think just about everyone does to some extent. In that way it can't be an easy job to scream what you believe is the truth until people listen. So really people like Mr. Naggum are giving up a large piece of happiness to continue their devotion to what they believe is truth. That's admirable.
