Did Martin Luther King, Jr., not face the world as it is? Was he delusional? Did he stand idle in the face of threats? This is President Obama’s position.
Did King oppose protecting and defending people? Of course not. He worked for that very goal!
I'm not a student of non-violence since I do believe that there are people who will simply attempt to kill you because they are simply out of their minds and have no regard for anyone's life, including their own. But in the larger arena Swanson and King have a good argument and if one is going to tell people in the streets to be "non-violent" by invoking King then one has an obligation to carry that same ideology into the world stage.
