The idealist in me agrees with David Bowden's little rap. The idealist in me realizes that no significant advancement of the human condition can be made unless there is a powerful and very often violent faction standing behind the forces that want to make the Earth a more "peaceful" (yes I know that it isn't consistant with my first statement) place.
For as long as man has walked upright he has never found a way to ensure peace except by killing those who he strives against. Is it sad? Why yes it is. Tell us how to change it and then you lead the charge for change but remember, NO violence.
