Lots of people are pissed off about the circumstances of their lives. I reject the notion that slavery, especially Southern slavery, has been the worst of all possible human conditions. So, for example, I would much rather have been Thomas Jefferson’s slave than to have been a coal miner in West Virginia.
At least the coal miner can choose to leave the profession. People who think slavery wasn’t so bad don’t understand the concept of being the property of another person.
I’ll grant that the plight of slaves in the U.S. wasn’t as bad as in Muslim countries as they weren’t castrated in the U.S.
Listen to the lyrics of Sixteen Tons sometime. And that song is about the 20th century, not the 19th.
