Jim is a somewhat heroic protagonist, is he not?
Yeah, and I remember that coming up in debates at the time. But the repeated reference to 'N… Jim" was just too much for many people. Also, I think some complained that he was a stereotype.
As it turns out, I leanred from @Banksiaman 's link that my district has pulled exactly zero books from its libraries. Color me pleasantly surprised. Nixa (a Springfield suburb/home of Jason Bourne) seems to have gone ham on banning books, however.
