As for the African/African Americans appropriating thing... Yeah, that article was based on what that lady perceived as appropriation, but was instead a bunch of Africans wearing African clothing.

As a Nigerian myself, I think a bunch of Africans need to chill the fuck out with their grudges towards African Americans.
