King believed that non-violence was the only way for spiritual people to bring about change because we should love even our enemies.
http://www.ipoet.com/ARCHIVE/BEYOND/King-Jr/Loving-Your-Enemies.html"Now first let us deal with this question, which is the practical question: How do you go about loving your enemies? I think the first thing is this: In order to love your enemies, you must begin by analyzing self. And I’m sure that seems strange to you, that I start out telling you this morning that you love your enemies by beginning with a look at self. It seems to me that that is the first and foremost way to come to an adequate discovery to the how of this situation."
Please go read this speech, it is wonderful. I wish had this deep understanding and love. One of my goals on my spiritual path is to discover an understanding within myself of outer conflicts. How can I love my enemies? Why are they my enemies? And what enemies do I carry around and hang on people I meet?
"A second thing that an individual must do in seeking to love his enemy is to discover the element of good in his enemy, and everytime you begin to hate that person and think of hating that person, realize that there is some good there and look at those good points which will over-balance the bad points."
