Schubert, very interesting observation. Never thought of it that way, bias always enter into the picture when dealing with humans. Taters certainly has a chip on his shoulder about Rap and Hip Hop, this is his third denigrating post in the last month or so. Give it a rest ...
With respect to "the grandfather of hip hop dies ..." I have no idea who he is referring to. I did a quick search and the only name I came up with is Gil Scott Heron, a name many of us here know, but he died in 2011!
