"...We can see evidence of this in the decades of Jim Crow that followed Reconstruction, when Black people were not only prevented from voting and denied access to a wide array of public accommodations but also, for the most part, kept out of the mainstream history profession...." JS

Let's leave aside his ridiculous remark that negroes were kept out of the mainstream history profession, which was a Northern white institution and tradition anyway, not a Southern one. 

He complains about negroes being prevented from voting in Jim Crow (as if Jim Crow were only a Southern phenomenon).

He fails to mention that negroes had been freed and given the voting franchise by the North, and during "Reconstruction" gangs of illiterate and befuddled former slave negroes were literally marched around Southern polling stations to vote multiple times for Grant in 1868, and were the only reason he won. This is only one example.

Negroes ran the South, as Yankee carpetbagger and Southern scalawag stooges, throughout "Reconstruction". 

During that time, they weren't denied anything that the Yankees could enforce letting them do or take over.

The majority of white voters, both North and South, wanted Seymour, a New York Deomcrat, not Grant, a Radical Republican thorough paced tool.
