The outdoor historical museum collection Greenfield Village near me in MI has a section of Civil War era buildings and examples of slave life and the small whitewashed cabins which were slave quarters in the South.
A history book about the attraction said in the late 1960s visitors came way saying “It doesn’t look like the slaves had it so bad. They had those nice little houses with cooking and beds.” Also a house like the one in The Jerk had a man paid to sing blues songs and folk songs on the front porch as a re-enactor. The curators had to reimagine the area and put up new narrative signs telling of the down side of being considered property and so on.

Michigan is, hands down, the worst state I've ever lived in but for Massachusetts. I refused to go to Greenfield Village in part because of the false history the leftists really really love to spout in that state. Any time I've been in a museum about Michigan history, it feels comparable to a museum in Turkey celebrating the victory of the Ottomans over Vienna in 1683 while explaining that the ottomans decided to grant mercy to Vienna and their devious allies the Polish Winged Hussars. Or a museum in North Korea proclaiming their supreme leader's victory over running dog imperialist President Eisenhower who kept his subjects oppressed and poor.
That said, I remember visiting the Smithsonian Natural History Museum in DC in 1987 on a high school field trip and then again in 1997 when I worked there. (Yes, although Michigan tries hard for the title, DC is still the most corrupt den of iniquity and awfulness in ... ever?) On both trips to the natural history museum they still had a plaque in the holocene era wing that proclaimed that the earth was cooling, it was caused by human beings, and we were all doomed to a new ice age. When I went again in 2000, that plaque had been removed but there was nothing to replace it. I haven't gone back since, but that's mostly because I hate DC, even more than I hated Michigan.
