And which myths would those be? Can you recommend any refeered publications to support your views?
For example, far from being the "Great Emancipator," as a lawyer he defended slave owners, helped create laws in Illinois that limited black civil rights, and throughout his entire life lobbied to have all Americans of African descent deported out of the U.S. He was even the head of the Illinois chapter of the American Colonization Society, an organization whose stated mission was to make America white from coast to coast.
During his two terms in office, Lincoln also committed countless crimes, among them starting a war without congressional approval, subverting the Constitution, illegally suspending habeas corpus, shutting down over 300 Northern newspapers, imprisoning or deporting fellow Northerners who advocated peace, and rigging elections. And this is just a partial list!
His partial list is enough to identify his scribblings as a work of fiction.
