Also ignoring that the various types of "white slavery" were in fact very different than the chattel slavery employed against African people. The kind of slavery we practiced in America treated (black) people as literal property. Including their own children, who could be born into slavery.

I'm not sure ignorance is the right word. "Willful disingenuity" is what leaps to my mind, but that doesn't roll off the tongue quite as easily.

Correct: It never really left.

It also really highlights how big selective enforcement is in this country, and puts that higher arrest rate for black suspects into perspective.

That doesn't change the fact that American slavery was one of the worst slavery businesses ever (and the bar is pretty low), hand in hand with the Arab slave trade
