“I’m sick and tired of violence… I’m tired of war and conflict in the world.  I’m tired of shooting. I’m tired of hatred.  I’m tired of selfishness. I’m tired of evil. 
I’m not going to use violence no matter who says it!”– Martin Luther King, Jr.
 
“Parents… have come to realize that children can be well behaved, cooperative, and polite without ever having been punished physically.”– Benjamin Spock
