I saw a an African American preacher on TV recently extolling the virtues of Donald Trump, complete with all the stereotypical intonations of the rural pulpit (can I have an "amen"?). That made me wonder whether such attitudes in the 21st Century, which of course strike me as self-destructive, might have originated in an earlier era. So of course I went to that font of historical truth, Google.
Using the search string "19th century black writers supporting slavery" I got the following result (graphic). I conclude therefrom that the preacher was just seeking his 15 minutes of fame.
