what you are saying is, the only objections (implying that these are easily brushed aside) are from the oppressed group that is still to this day not only victim of this word on a regular basis, but still subject as a group to the on-going disenfranchisement policies regarding african americans in this country. from mandatory sentencing based on drugs considered more common in POC communities, to predatory loan practices aimed at african american families specifically, to stop and frisk policies that mainly target minorities, etc etc etc. 

that is one article. if you google that song, you come up with countless critiques by POC social justice activists ripping it apart and all of the implications and causations of it. i feel competant you can do your own research to figure out why this is a bad example of groups not affected by slurs attempting reclamation of those terms by majority privileged groups.
