I think it's really crucial to leave our American context, not only for a sense of individual freedom, but also to make links to international struggles for civil rights.

Here is a pragmatic and idealistic suggestion, White America! When you see my kids on the playground, on the street, can you remember to smile at them as you would smile at your own? Because believe me as your better angel already does they are every bit as lovable.

I don't keep from despairing. I let myself despair. I just don't linger there for too long. There's too much to laugh about, two knuckleheads I have to feed, and a lot of really excellent television to watch. I think the mess we're in deserves the full range of human feeling, from despair to its opposite, which I would say is not hope, happiness, or peace, but freedom.

Your average white liberal might agree with social justice in principle, and yet live quite comfortably as a "winner" in a nation whose social institutions - characterized by political exclusion, exploitation, and unequal access to resources - have systematically made others lose out. But here's the thing. Maybe it's time to get uncomfortable and upset. Maybe those feelings can be acted upon.

I felt saddened and confused to discover my favorite mural gone, but also hopeful that another one may be in the works. Street art is mysterious and impermanent like that. It can appear or disappear overnight. Murals like these are at risk of desecration, transformation, erasure. Someone's gonna piss on it, draw a mustache on it, tag it. The weather's going to make it fade. That's part of the beauty, I think. Murals have value without being precious.

I learned from James Baldwin that one can be a novelist, essayist, and activist, combined. That being critical of one's country is a way of loving it. That travel is crucial for perspective. That faith needn't be confined to organized religion.

Nowadays we can sidestep traditional media with social media and technology that allows us to become citizen journalists, to fight against injustice by showing what's shamefully going on.
