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 look at my kids, who were born under a Black president, who hop around the living room naked and joyful, mimicking Simone Biles, and just think, Damn, they got some amazing role models of Black excellence.

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.

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.

Acknowledging the realities of structural and institutional racism is hard for conscionable white people. It might ask them to consider how they're personally implicated, or have gained from systems that have oppressed and rejected others. It might require them to take a next step. It's easier to say, "I don't see race," or to dismiss the Black Lives Matter movement as structureless and theatrical than to embrace and promote its most basic premise, which is to believe that black lives have worth.

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.

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.
