SHOOTALL, you're right on, as usual. I will go a bit further.
Bucksin said the northern people of today don't hear or talk about it, but they hear about it if they come south. Why is that? Get a grip. It's a matter of culture. Northerners are all in the fast lane. They talk fast, they're rude to each other, selfish and self centered, for the most part. They don't have time to mess around with what their ancestors screwed up. They must get on with something else to screw up, like dealing with the northern slums that are the worst on the plantet. Except they don't deal with it. They allow it to continue unabated because it is in their culture, in their very nature, to give freedom to the abused even if they can't now help the descendants of the abused, most all of whom in said slums are still expecting to be taken care of by the big government they voted for. The most energetic of those down-trodden victims survive via the many alleys and avenues that criminals might take, all of which byways are teeming with rats and roaches and the worst of humanity. The disgusting menace that makes up the northern populated regions are what the northerners have as a "thank you" from their 1860's aggression.
I'm not about to watch the Lincoln movie. Anyone who can be influenced by a movie, or who needs a movie to reinforce their twisted beliefs, is probably a yankee.
