That is true, but liberals and the "lookin to be offended" can find racist dwarves, racist elves, racist orcs, racist wizzards, racist hobbits, racist Numenorians, racist Gondorans, racist Riders of Rohan...et. al...even in a fantasy.
Snow White was probably a racist, and Cindarella was probably an elitist, Robin Hood was a liberal Democrat, Pinochio was making fun of Al Gore as a boy...and on it goes
