Re: LOTR: Racist?
I don't think Tolkien was racist or sexist.
Considering the times he wrote in, I think he was remarkably broad minded.
He portrayed strong female characters and used multiple races and motivations to convey his story when it would have been very easy to have stereotypical blond norse warrior heroes everywhere. It's too his credit that his most memorable heroes are the antithesis of this.
As for the movie version, there were lots of "dark" gondorians in RotK - after all, they were mostly Kiwis!
Even the Elves and Rohirrim are much less uniform than portrayed in the novel.
As for the bad guys being asian-looking....they are from the east! If they were going to look different from the european looking gondor/rohirrim/shirefolk, they were going to look to go elsewhere for inspiration.
I think people line up to knock Tolkien for some reason.
