If you didn't listen to the MLK "I have a dream" speech today, that's a shame.  Actually, go listen to it right now, then come back. I'll wait.

All right. You probably never noticed this before, but it's much more than a plea for equality.  It's a plea for justice for all people.  Justice.  That word is found a dozen or so times in the first half of the speech.
Blackey-black-black and whitey-white-white can argue about equality. They can get blackey-white-white and whitey-black-black or blackey-white-black and whitey-black-white to join in the fray. Even blackey-black-white and whitey-white-black will get provoked to take a side now and then.

But they must all side with justice, or else.  You don't want justice for all in this world? You want to look out for your own and to hell with the rest?  Then, you're an asshole. You're un-American. And everyone around you will know you as an un-American asshole long before you figure it out way too late.

Welcome to the Bloomsday Device.
