I may be wrong but, I must believe that you are not judging all by the actions of some.
Also that Dr. King Jr.'s desire to see blacks become contributing members of society has been derailed by race baiters and politicians.
While I take your meaning, isn't that sort of the same sort of generalization? Look at folks like Colin Powell, Allen West, Ben Carson. Hell, look at the black neighbors on my cul-de-sac. Making a life for themselves and their families; not consumed by hatred and despair and suspicion of their white neighbors. Seems to me that THAT is what MLK was hoping for "his" people - to be TREATED like "people." Yeah, there is a loudly vocal segment of that group that makes normal folks look bad to the rest of us, but, again, the proper thing to do is judge individually - not prejudge widely. (And this coming from a guy who wondered out loud how to tell "good" Muslims from "bad" Muslims.)
