Above all, be an honest person of integrity that deals fairly with all, and repairs any harm done to others. Lastly, we can dust off a word that was put away too soon - Abolition. A good, hard, uncompromising word, rich with historical overtones. The institutionalized coercion of some individuals by others is still with us. Perhaps we were naive to think that freeing the slaves brought from Africa would be the end of a poisonous idea.
Ideas die harder than that.
It may be that, if we ever completely abolish slavery, the state as we know it will cease to exist. I'm sure we can think of something better. Of all tyrannies a tyranny exercised for the good of its victims may be the most oppressive. It may be better to live under robber barons than under omnipotent moral busybodies. You start being 'kind' to people before you have considered their rights, and then force upon them supposed kindnesses which they in fact had a right to refuse, and finally kindnesses which no one but you will recognize as kindnesses and which the recipient will feel as abominable cruelties.
