Slavery was cancerous but does anybody regard cancer in the United States as an evil peculiar to American society? It is a worldwide affliction and so was slavery.
Both the enslavers and the enslaved have included people on every inhabited continent — people of every race, color, and creed.
More Europeans were enslaved and taken to North Africa by Barbary Coast pirates alone than there were African slaves taken to the United States and to the colonies from which it was formed.
Yet throughout our educational system, our media, and in politics, slavery is incessantly presented as if it were something peculiar to black and white Americans.
What was peculiar about the United States was that it was the first country in which slavery was under attack from the moment the country was created.
What was peculiar about Western civilization was that it was the first civilization to destroy slavery, not only within its own countries but in other countries around the world as well.
