> We really need to peacefully explore the "national divorce" idea again. In the 1860s the concept was too intermingled with the evil of slavery to be considered separately.

The idea is still just as intermingled with fundamental human rights, plus the sides are more deeply geographically intermingled than in the 1860s, largely because the victors decided not to really root out the evil they had defeated an instead allowed it to metastasize. There may be no peaceful resolution; there is certainly no possibility of a peaceful divorce.
