By that, I meant you can't compare the hardships of a free person to that of a slave. In the end, a free person, if all else fails, they were free to pick up and leave in search of a better life. Even an attempt to do so could mean torture, dismemberment, or even death for a slave.
And it is completely untrue to say that you can't repair the damage leftover from slavery. You can only pretend there was no damage done. Which is also completely untrue.
Freeing your kidnap victim is not payment for having kidnapped them in the first place. As Malcolm X said, If you stab me with a 9" knife, pulling it out 3" does not help me. If you pull it out 6", you still have not helped me. If you pull the knife all the way out. You still have not helped me. Until you aid me in healing the wound, you are in fact refusing to help me.
