What would it take for you to willingly become a slave?
Availability of options when one makes choices determine what these choices are. Like I indicated, there weren't any other options other than death for those whose were shipped to America. No one at the time could foresee that their descendents would be the lucky ones given the opportunities that exist today. This is not defending slavery. This is stating a fact. If you disagree with that fact, state your case. See if you can state it without the "slavery is rotten" argument because you and I both agree that it is.
