my friend I see a lot of people either attacking you or at the very least side-eyeing you but without giving you some sort of answers
I will preface it by saying I'm pretty sure other members of the forum who are African America can give more context to this but I'll add what I know from my personal experience
there is so much nuance and background and history to black culture in America that there is no change in hell I could explain anything in detail on a kpop forum - from the times of slavery to modern system racism African Americans have faced a lot of hardship and adversity in the perseverance of their identity.
And thus SOME African Americans feel like there are certain aspects of themselves that is very unique to them and them only. For example (this is not a definitive list and not all African Americans would agree but generally from what I've seen)
Hairstyling - very unique ways of caring for their hair and the use of certain braids
Speech - a few years ago I learned what AAVE is and the way certain African Americans speak that is not perfectly "standard English" for example I have an African American friend who says aks instead of ask as an example
Clothing - for example the durag which I learned was used for hair protection ( I learned this during the Lisa durag vs bandana issue lol)
Music - Hip hop and RnB are deep rooted in black culture and SOME (lots??) of African Americans feel that these are unique to African Americans and their history
Again this is not an exhaustive list and there may be much much more
the difference between that and say Chinese culture (which I am Chinese) again from my own experience is that foreign entities have not (especially in mass) tried to use Chinese culture for their own gains to the detriment of said Chinese. and thus the Chinese were happy when other foreign entities used aspects of Chinese culture
for African Americans though it is often the adoption or use of their culture TO THEIR DETRIMENT historically and often to the benefit of the foreigner or outsider and thus to African Americans it seems that such use of aspects of their culture strips away something that is unique to them and their identity
Again I am but an outsider to all this and the more knowledgeable members of the forum especially those from the US can provide more insight into this issue.
to all the people having a go at girlgroupstan21 I say - try to enlighten them on the issues surrounding this very complex issue instead of going after them so that in the future they can (start) to understand the issues a bit better
