Why would you say this in Minnesota? People there don't give a crap about Confederate statues.
Northern states are full of hicks who proudly display Confederate flags despite their own ancestors were shot by people brandishing those flags. Trump rallies are where you are as bound to find those morons as anywhere.
Wrong.
You can't just say something's wrong because you haven't personally experienced it. I can tell you there are tons of Confederate flags in rural PA, MD, NJ and upstate NY. Nowadays they're more likely to be accompanied by the blue lives matter and the no steppy on snek, but they haven't gone away.
Further proof that the true divider between north and south is not the Mason-Dixon line, but rather I 70.
Yankee and Dixie settlement patterns in Ohio are two much of a chess board pattern for a single line to effectively represented pro-Southern views during the Civil War. There is also the hour-glass/bowtie shape in PA that I have talked about, where the sides of the bow tie are pro-confederate and the right one even has an arm reaching up towards Albany where a combination of Irish, Dutch and other Non-Yankees formed a bastion of opposition to Lincoln though it is debatable how pro-Southern that group was versus just being pro-Democratic against a "Yankee-dominated" Republican Party.
