Who knows?
All I know for sure is that you can call me pretty much anything as long as you smile.
I think the black community is having a serious discussion with themselves right now. A healthy one about the meaning of the King legacy, Jackson, Sharpeton, etc. The barbershop movie brought the discussion to where it was visible to the whole nation. Maybe this shirt is a sign of the changing times. Again, who knows.
I do have one opinion about this: that they should be left to themselves to sort it out. Any sort of politicizing of it by whites will just make it stop.
