I don't think she should be congralutated for stating the obvious, especially since she herself is a white girl. It kinda brings that white savior aspect out of it too, like people will only pay attention and condemn Miley for what shes doing if a white person says it's racist and wrong.
White people shouldn't talk about other white people appropriating, being racist, or being culture vultures, unless they themselves are gonna stop doing it and crushing the system that puts them above the people who's culture they completely stole.
A white girl is stating the obvious and calling out another white girl for being racist and appropriating what she deems to be black culture, and we all listen. Let this be some Janelle Monae/Lianne La Havas/India Arie type chick and ain't nobody listening.
That's the problem. It's the white savior complex, she wanna come in on some "She's disrespectin your culture, I'm callin her out, congratulate me everybody I'm here to speak on behalf of all the disenfranchised black folk she's using as accessories and makin paper off of". Like gtfo I don't need no white bytch tellin me nothin.
