Why would you post a video of the Neimoidians speaking to bolster your argument when they clearly sound like a stereotypical Asian person? That’s like arguing as to why you think Han isn’t a good pilot and posting a video of the asteroid chase. It would be counterproductive if you ask me.
EDIT:
And whether you think it is or isn’t racist or if George is racist or isn’t racist doesn’t matter…the Neimodians are still a racist caricature without a shadow of a doubt.
