But, inadvertently, it sounds like you and Lillith are saying, "I don't have a problem with it ... but it's wrong, she shouldn't do that again." You're contradicting yourselves.
I don't have a problem with the girl's hair: she's a child, she meant no harm or insult, she was wholly unaware of the recent history of such braided hairstyles, and I have no personal affiliation with the black/African culture and thus cannot experience any personal insult. However, I do have a problem with cultural appropriation in general, with the fact that a sector of the population have lived for decades with "it's ghetto and trashy when black women wear it, but it's chic and sexy when wihte women wear it", and then are further insulted and demonised by "it's meant as a compliment!" and "what's wrong with
those people!" and "PC police gone mad!" and "
I wouldn't feel offended, so they shouldn't either!" comments when discussions of cultural appropriation occur.
