No.
Because you sure are creating a new one.
No, I'm not.
The Great Migration didn't take place until 50 years--half a century--after the end of the Civil War.
I didn't mention any "Great Migration." You did.
In 1900, approximately 90 percent of all blacks still lived in the former slave-holding states.
Kind of destroys the argument that the slave economy was so horrible, doesn't it? After all, why stay down on the plantation when the streets Up No'th are paved with gold?
Detroit's black population in 1910 was all of 6,000, just 1% of the total population.
I used Detroit as a metaphor for ALL the Northern industrial centers. And I never said that only Blacks were serfs in the industrialized North. In fact, I argued just the opposite.
freed slaves who stayed in the south continued to be disenfranchised, once Reconstruction ended and Jim Crow laws were enacted.
Discrimination -- whether codified in the form of Jim Crow laws or exercised de facto as a cultural artifact -- existed, and continues to exist in all parts of the country. To suggest that it is limited to the South is simplistic.
