if Apu is offensive because of the accent, and because a white person is doing the voice, and for being stereotypical
Then there is another character that needs to change due to being equally offensive as well
how long is it going to take for someone semi famous to bring up the same issues that makes Apu a bad character? what will universal do when controversy strikes?
you could make the same arguments with Mario than with Apu. specially the fact that a white man is doing a "funny voice" of a character from a specific place.
