This is a  shorter version of a talk I gave at Rochester's Institute of Technology in honor of Dr. Martin Luther King, Jr.  In it, I discuss why we in America are encouraged to remember some events, like 9-11, but we're encouraged to stop talking about other things, like slavery, Jim Crow and current racial issues.  It's crucial for us as a people to remember all of our past, not so that we can become bitter, but so that we can better understand others -- and prevent history from repeating itself.
