According to Blayney Colmore
We were required to take part in a training by the Fellowship of Reconciliation. To this day, I carry in my wallet the handout they gave us. Burned into my memory is their teaching about real revolutionary change, the toughest standard I have encountered before or since:
When confronted by someone who opposes your view, picture where in your solution to the problem your opponent fits. If there is no place for him, it is not a revolution, not greater justice, but merely replacing his tyranny with yours.
