HamdenRice's article is entitled, "Most of you have no idea what Martin Luther King actually did." Yes, that's a confrontational, but it's also right.
No matter what your ethnic background, you should read that article. It will free you from seeing Dr. King through the "Care Bears" lens our culture's crafted of him, disabuse you of thinking "all King did was march," and force you to consider the kind of world African-Americans faced daily before Dr. King got to work. The article will also help some people understand why African-Americans are so protective and possessive of King's legacy. And that's all I'll say because I don't want to give anything else away about the piece. Just please read it!
On another note regarding general ignorance about Martin Luther King Jr., CNN's has an article up entitled "The greatest MLK speeches you never heard." If the only thing you know of MLK is the "I Have A Dream," speech, then read the CNN article, too, and if that is the case then you definitely need to read the article at Daily Kos.
Happy Martin Luther King Day!
I hope we all use it as a day of service and reflection.
