Acknowledge this also:
Slavery was a fundamental part of all civilizations, from the dawn of history until the 19th century, when Western Civilization outlawed slavery!
It is Western Civilization--including Great Britain and the United States--that made slavery illegal and eliminated it from their jurisdictions!
Slavery is one of the most hideous evils ever devised by man or the devil!
Unfortunately, slavery still exists in the world today--yes, in the 21st century--but NOT in the nations in which Western Civilization and Christianity prevail.
Those interested in fighting against this hideous evil might want to support the American Anti-Slavery Group. This is an abolitionist organization dedicated to fighting against and eliminating slavery from the face of the earth.

and make no mistake if western civilization were ever to fall, slavery would be back instantly.
Actually the westerners would BE the slaves.
