Gee, when are you going to talk about Black Codes in southern states, the part that the south played in the slave trade, and laws meant to keep free blacks from emigrating into southern states?

The truth doesn't hurt, only the attempt of some (not meaning you) to paint the South as participating in illegal actions while refusing to acknowledge the participation by the North. Both sections of the country ratified the Constitution - both in favor of retaining the slave trade, and considering slaves to be non-persons/citizens.

Sure, but while I in no way want to portray the North as an innocent party in all this, let's not also forget that the south was also an enthusiastic partner in the slave trade and the south had legislation restricting the freedom of free blacks that was more restrictive than anything up North.
