Phil in SF commented on Pastwatch by Orson Scott Card
Orson Card flipped his lid at criticism that his Ender series was a Hitler apologetic, so he followed it up with a book explicitly subtitled "The Redemption of Christopher Columbus".
Philip Weiss (Phil in SF) replied to Phil in SF's status
When Pastwatch came out, I was starting to figure out that Card was a political heel, but I hadn't quite figured out that his writing was in service of his political aims.
