I have always liked Colin Kaepernick. As a quarterback, he has a flare for the unexpected, the dramatic, the improvisational. But now I Iike him even more, not for his football prowess, but for his humanity and courage. It takes guts to sit when you’re expected to stand for the national anthem, while millions are watching. But in sitting he has reminded our country that it will not be let off the hook until it attends to the racism that is deeply embedded in the criminal justice system and every other aspect of American life. Agitation for justice isn’t always pretty, but history tells us that it is absolutely necessary.
