As a black man, I don't care about the appropriation of black culture, so long as it's not done as a means of deriding it or cashing in on it. Some artists are more guilty of doing this than others, but sometimes it's difficult to draw the line between what is genuine appreciation of a cultural aesthetic and what is patronizing it. Likewise, I don't think all black musicians are exempt from also cashing in on the aesthetic to make record sales.
It's an issue worth exploring, but in the grand scheme of things, it just seems considerably less important than other issues affecting blacks in the US. A large segment of the popular music industry is motivated purely by what sells and what the flavor of the week is and elements of black culture are always popular go-tos.
It doesn't incense me that some people see Iggy Azaelia as "running hip hop" or to see Macklemore sweep the rap categories. Regardless of their roots or authenticity, they garner fans. I may rather listen to "oldies" like Black Sheep, Tribe or O.C., but I don't fault those that are able to succeed within a genre regardless of that genre's roots or the artists' skin color (although, again, it bugs me if they utilize black culture as a means of selling their music and not because that's just who they are).
