Non-violent direct action seeks to create such a crisis and establish such creative tension that a community that has constantly refused to negotiate is forced to confront the issue. It seeks so to dramatize the issue that it can no longer be ignored... I am not afraid of the word tension. I have earnestly worked and preached against violent tension, and there is a type of constructive tension that is necessary for growth.
