When whites fail, they fail. Nobody hesitates to say that they were lazy or drunks or dopeheads or "shiftless," whatever. We seem to feel obliged to pronounce racism as the first and foremost reason why blacks fail. It sets up a straw man for them to fight against when their focus and energies should be elsewhere. It also provides a ready excuse not to try as hard.
As intended, it creates another Hegelian conundrum for us to argue about, to wit: If someone is being bullied and they eventually knuckle under, do you blame the bully or the victim?
All I know is that I wouldn't want to be a black person in America...especially an inner city black resident.
...then again, I wouldn't want to be me, either, if I had a choice. :-?
