What Martin Luther King did

This was painful to read but I thought it was worth it. And the writer is correct with respect to me—I had no idea that's what he did.

Excerpts (emphasis in the original post):

...this is what the great Dr. Martin Luther King accomplished. Not that he marched, nor that he gave speeches.

He ended the terror of living as a black person, especially in the south.

I'm guessing that most of you, especially those having come fresh from seeing "The Help," may not understand what this was all about. But living in the south (and in parts of the mid west and in many ghettos of the north) was living under terrorism.
