Sadly, your post will be in the minority on this thread.
We can fairly judge the past by the standards of President John Adams, who called slavery "an evil of callosal magnitude." We can discern eternal standards in the deeds of William Wilberforce and John Quincy Adams, and Harriet Beecher Stowe, and Abraham Lincoln. These men and women, black and white, burned with a zeal for freedom, and they left behind a different and better nation. Their moral vision caused Americans to examine our hearts, to correct our Constitution, and to teach our children the dignity and equality of every person of every race. By a plan known only to Providence, the stolen sons and daughters of Africa helped to awaken the conscience of America. The very people traded into slavery helped to set America free...This is fantastic stuff.
