It's been over 40 years since Dr. King delivered his speech from the Lincoln Memorial. Read it, every word of it, and see how far we've come.
There are those who say we haven't come far enough. I don't agree with that, especially from a standpoint of law. In King's day there existed the segregationists, today we have the preferentialists; both are wrong, as they're opposite sides of the same coin. Look at the specifics Dr. King mentioned in his speech, look at our country today, and tell me what you see.
There are those who will point out statistics about black Americans--this is not the place for that, and this is not the day. It is for us today to rededicate ourselves to the principles of which Dr. King spoke, and which were enshrined a year later in the Civil Rights Act of 1964. It is for us today to give thanks that men such as Dr. King have walked among us.
He started that walk on this day, in 1929.
