NPR has an excellent article about a swamp in the Virginia and North Carolina area where slaves fled to escape brutality. Today, we read how ISIS, the Islamic State, defends and promotes slavery and the abuse of slaves (particularly women) in the 21st century. If this is shocking to you, I encourage you to use this to understand why slaves fled similar abuse in the United States. This is important because I have heard White Americans defend slavery in the United States in the 21st century.
Bottom-line: There is no excuse for this sort of ignorance or hatred of our neighbors.
