When the topic of racism comes up, I often think of a billboard in the small town of Harrison, Arkansas.

It was a sign promoting a white supremacist radio station called White Pride Radio. The sign’s message, emblazoned next to the picture of a cute-looking white girl with a cute-looking dog, read “It’s not racist to [heart] your people.”

My takeaway: Even white supremacists don’t want to be called racist.

Which might explain why, for people dedicated to fighting racism, simply saying you’re “not racist” doesn’t feel like quite enough. To effectively defeat systemic racism — racism embedded as normal practice in institutions like education and law enforcement — you’ve got to be continually working towards equality for all races, striving to undo racism in your mind, your personal environment and the wider world.
