We have indeed come a long way. As of this week we have a black man in the White House, but as sure as I've had more than one person tell me "Well he's only half-black," we definitely still have quite a ways to go. Public Enemy's incindiary response to Arizona's refusal to recognize Dr. Martin Luther King Jr.'s birth date as a holiday serves to remind me that we aren't that far from a time where Obama's presidency was unfathomable. Just because Obama's our president doesn't mean we need to lose the capacity for the type of fire that Chuck D carried in his words. The events of Tuesday were only possible through the years of effort and sacrifices by great people like the one we honored the day before.
