> The South was not in general convinced by the emancipation proclamation, and so the oppression continued in the extreme.

It's a better example to point out that the the emancipation proclamation didn't even free all the Union's Slaves at the time. Its kind of a no-duh that the South wouldn't follow it because the emancipation proclamation was a war measure against the Confederacy. Edit: It'd also be stronger to point out Jim Crow laws in the reconstruction era
