Martin Luther King Day
There are several facets you might need to examine when studying the Rev. Dr. Martin Luther King, Jr. (sometimes I wish my name was that long). There's the sunny, "I Have A Dream" third-grade approved sanitized version, there's the politically active speaking-out-against-Vietnam version, there's the wracked-by-scandal version, and finally, there remains simply the man.
I'm not sure if King was a great man. I hold far lower opinions of people like FDR and Lincoln than most of my peers, and, in any case, I'm no judge of moral fiber. But, since I get a day off, I'm willing to give him the benefit of the doubt.
