"To my parents freedom meant above all, "Live and let live." They were willing to settle for tolerance. For the world in which you are going to live, tolerance will not be good enough. We are now in the "Live and help live" era of democracy. Like your immigrant grandparents who sent for those left behind, you will have to help others to cross over into freedom."
