A Daily Kos diary by HamdenRice dated 29 Aug 2011 crossed my radar this morning (Martin Luther King, Jr. Day in the United States), thanks to a FB friend with whom I worked briefly in a Bay Area activist group (he now lives elsewhere). I have nothing to add to the unadorned link, below, other than the hope that more people read it because of this link than might otherwise find this piece.
The diary: Most of you have no idea what Martin Luther King actually did.
It's one of the most powerful accounts of how political activism transforms the world that I have ever read in the essay form.
Thanks to CJ for pointing me to HamdenRice's diary on Daily Kos; and to the Minnesota Historical Society and Wikimedia Commons for the image of Dr. King.
