@TOOLFRENZY: Not really. You could say a character is a stereotype of a white guy, but there will be numerous other white characters that won't fit the stereotypes. While with Apu it doesn't do much to show that Indian stereotypes aren't a universal truth.
I doubt even you are that divorced from reality, but just in case: The Simpsons is an old cartoon show, not a source of universal truth about ethnicity.
You're right that it's an old cartoon show, but so what. Art doesn't exist in a vacuum. Do you think the tropes and characters from The Simpsons came out of thin air, like magic?
You clearly don´t understand art if you think Simpsons is art. Not to mention if you think art should be changed because suddenly the climate changes and someone feels offended.
And of course the Simpsons didn´t come out of thin air, it comes out of comedy and from a time where people laughed instead of censoring.
