Hot take: If you’re white, you’re not allowed to cosplay anyone from Avatar: The Last Airbender.
It’s cute that you think you have a say in what other people do….
I really want to see one of these people try to stop someone. I will pay to see them try.
If you’re black, arab, South Asian, East Asian, Pacific islander or hispanic, then you cannot cosplay anyone from Disney’s Frozen. Oh wait, non white people do that anyway. And whites cosplay people from ATLA all the time. So who gives a shit?
