I think one can easily take all these things far too seriously. Can idiots and bad guys only be white? There's a difference between a character that's just silly and one that's clearly intended to portray a whole people as such. I don't believe Jar Jar was such a character. Remember that movie that came out a year before TPM? It was very popular, Disney, and had an idiotic racial character named Mushu. That's right, I'm talking about Mulan, with Eddie Murphie's dragon calling a horse a cow and being a horrible klutz that nearly ruins everything by destroying the Stone Dragon among other things. Everyone laughed. No one called this film with it's poor portrayal of ancient Chinese culture racist. No one complained that all the Huns were an evil and heartless people who murdered without second thought. Why?
