The world's great spiritual masters have been teaching us to "love our enemies," and to "be the peace we want to see in the world." What makes the human species special is our ability to evolve and grow toward greater virtue, to move continually forward with a goal of non-violence and cherishing all living beings. We do not want to have students going to class with killing weapons and if we are still wanting to carry killing guns in the year 3,000 maybe we aren't so special after all.
