I'm struggling to see what all the fuss is about other than a knee jerk reaction to cry 'racism' because some people have decided to campaign on what is seemingly a pretty trivial issue?
latest example here:

Firstly the comparison to black face is ridiculous... black face actually sets out to mock physical features of black people in the same way Nazi propaganda used to mock Jewish people. On the other hand costumes, which is all Ellie is using the outfit for, mostly do tend to come from one culture or another.
I don't see Italian or Greek Americans getting upset over Toga parties, Texans getting upset over cowboy outfits, Irish people getting upset over green hats and ginger beards or people with European heritage getting upset because someone has chosen to wear ceremonial robes and crown like a European Monarch. What makes Indian Chiefs so special that their manner of dress becomes offensive when copied for a costume over the many other costumes that come from various cultures?
