To be fair, slavery has existed world wide throughout human history and there are open air slave markets today in North Africa. In America we fought a bloody war that took many lives which deserves to be seen as some sort of reconciliation. Is slavery wrong? Of course but they, as we, were subject to their zeitgeist. The all created equal was and is an aspiration, a goal that due to the flaws in humanity may never be fully achieved, but is still a goal. As long as Americans view social justice as a zero sum situation where Peter should be robbed to pay Paul we will never be free.
