What I celebrate him for, more than anything, is that he reminded us how to handle injustice.
He did not handle injustice by attacking it, or by blaming others for it, or by taking it to the courts, or by running from it, or by despairing in its face.
He dealt with it by naming it. Again and again, in the face of scorn and threats and violence and discrimination, he stood up and he called it what it was. He said "this is injustice".
It really is that simple.
After a long while, people listened to Martin, and they looked, and they saw injustice.
It's not all gone. But after Martin, it couldn't hide.
Happy Martin Luther King day. Name the injustices you see.
