I think a few here is fond of the old Franklin Delano Roosevelt, but looking into the actions that he did during the years into the prelude of World War 2 was really interesting. At his behest, he supplied Joseph Stalin and the whole Soviet Union of military equipment and intelligence to prepare for the Nazis. I really don't think that Americans during at the time was on board with supplying another enemy, the communists, with their own handmade products just to hold off the Reich.
Let's not get started with the internment camps he did against Americans of Japanese lineage after the Pearl Harbor attacks, how the Democrats were tight-lipped about it to this day, and the communist project that the former First Lady, Eleanor Roosevelt did in Arthurdale, Virginia, that was still left untold on how many people died due to starvation on that god forsaken experiment of hers.
None off the top of my head, but they exist since Bleeding Kansas is one of the causes of the Civil War. A lot of it is stuff I learned just from living here, doubly so because I live in the Eastern Kansas, which is where most of the fighting happened. I actually live near the Beecher Church (the abolitionist who brought the guns in). And yes, this is the same Beecher family that wrote Uncle Toms Cabin.
