I don't see the need to know in the blacks I've encountered. Everything is pretty much shallow, they don't look to dig very deep.
They might know that Usain Bolt is fast but they can't talk the history of Jamaica sprinting, yes yes....they really don't care, which is my point. They can't talk Herb McKenley, Les Laing, George Rhoden. They just aren't interested. But.......a lack of interest has nothing to do with intelligence.
I had a grandfather who could cook better than any woman I've ever known, an ace mechanic, could grow anything, play the guitar, fix anything, he wouldn't have a clue who ens, Poe, Fitzgerald, Steinbeck, London were.
