I don't know a single thing about him, besides him being a rapper, but he is speaking the truth. Good for him for being a mature man who looks at the big picture. There would have been no freedom for blacks if not for white people dying to give it. Not to say we were alone in this either. It took blacks fighting and dying too, and other races. This is known.
We all can take a cue from him, regardless of color. Stop demonizing our fellow man, regardless of color. This seems simple to me, and I hope it catches on, though it doesn't seem likely. We love to fight about race too much.
