“If we can change “white people” to slaveowners, I’m all for it.”
To these racists all white people are either former slave owners or want to become slave owners. That is it. All white people fit into one of those two groups. And that makes it OK to prejudge all white people.
That is correct, although it shows an appalling ignorance of history.
In actual fact, we are probably all descended both from slaves and from slaveowners.
My personal default position is to side with the slaves against their owners. Slavery is the permanent institutionalization of theft and kidnapping.
