I have always loved the Clint Eastwood movie The Outlaw Josey Wales, but a couple of articles I read today about the author of the original story blew my mind. Apparently this was the same person who wrote George Wallace's infamous inauguration speech!
Here is an article from NYT: https://www.nytimes.com/1997/12/17/movies/movie-with-a-murky-background-the-man-who-wrote-the-book.html
Also this one from Dissent: https://www.dissentmagazine.org/article/cowboy-confederates
