AAkidsRacism is a topic that my heart keeps returning to. What is it? What causes it? Why is it so hard to escape?

Why do many white people from outlying areas of my city avoid driving in predominantly African-American sections? Answer: They tell each other that the city people are murderous thugs, out to prey on strangers. It’s very dangerous. Never mind that the statistics don’t bear them out.

What did Hitler tell the Germans about the Jews that led the Germans to turn their heads when their Jewish neighbors were marched away to their doom? Answer: Hitler told them the Jews were manipulative, dangerous, and powerful. Never mind that the opposite was true.

Racism comes from fear, and from unfamiliarity. People become convinced that those in another group are not to be trusted and might do terrible things if you let them.

Racism is based on the innate fear of strangers that we all have. Once someone is branded a stranger, we decide they might very well hurt us, and we don’t care about defending their rights. It’s us vs. them. War. They seem less than human to us. Demonized. Other. Not in my tribe.

We’re all fearful of strangers. Including me.

So, how do I combat racism in myself? A good start would be to make a decision to adopt the other-person into my tribe, in my own mind. A decision to look this person in the eye and deal normally with them. A decision to reach out.

Mostly those who experience racism are in minority groups. So those of us in the majority have a lot of trouble believing it’s a problem. We’ve hardly experienced the short end of the stick. So we declare everything’s okay.

But ignoring the situation doesn’t mean it goes away.

In my city, St. Louis, we have unofficial dividing lines for neighborhoods. On the north side of the central east-west avenue, Delmar Boulevard, are mostly black folks. On the south side, mostly white. Sure, we’re all free to move around these days, in a way that wasn’t possible in the 1950s and before.

Nobody is chaining us to the places we live—unless we are too poor to afford to move. And with that poverty comes poor schools, without the taxpayer support that the outlying areas enjoy. And without a good education, no way out for those who want out.

This is not a post-racial America.

To make a difference, each of us needs to make a habit of reaching out beyond our comfort zone. How will you do that today?
