Justice should not be based upon the rules of old men many miles away, enforced by young men with a gun on their hip and an authoritative glean in their eyes.
No, justice is a personal thing, and should be ironed out between individuals every day in the ways they interact. Justice should evolve, just as all human relationships evolve.
Liberty is the power to do what you want with the things you have so long as you do no injustice to others.
To give lip-service to ‘liberty and justice’ via the Pledge of Allegiance without understanding them numbs the mind to useful concepts.
