In my opinion, the article "a word on artistic political correctness" have a good point. I agree that the cultural appropriation needs to stop. However, the article doesn't awnser its question: " How do we balance or even differentciate cultural appropriation from cultural appreciation?"
To awnser that question, we can think about movies for example: many of them have esteriotypes of other cultures and bad representation of people from other countries. That's the point: We need to represent other cultures with respect.
I've seen many videoclips that have tradicional clothes out of context just because it's "cool". In summary, if it doesn't have a reason for these representations, it's just culture apropriation.
