I moved to Boulder, Colorado, from Washington, DC, a little more than a year ago. There are a lot of wonderful things about living here. It’s beautiful, the weather is usually great (minus our biblical flood last month) and the people are incredibly nice (they don’t even honk when they have every reason to). But racially and culturally diverse it is not. And in the past I’ve noticed that when you don’t have a lot of experience with people of difference races, ethnicities or religions, you are susceptible to sometimes doing and saying things that reflect a lack of awareness. That’s why I was really relieved and happy to see this awareness campaign at the University of Colorado for Halloween. It doesn’t blame people for being stupid or assume they’re bigots. Instead, it shows how an ignorant attempt at being funny can reinforce racial stereotypes and reflect a personal ignorance that can be really hurtful to others. What’s particularly important about an institution like the University of Colorado doing this campaign is it takes the pressure off students who are in the minority. Being the one of anything among a majority can be exhausting and frustrating because it’s hard enough to feel comfortable in your environment without calling out people every time they say or do something stupid to you or about you. As a parent, and especially if you live in a community where most people look the same, these are the kinds of spontaneous moments you can use to concretely impart a lesson about racism. Show your kids the Colorado campaign. Ask them what they think about it. Then tell them how you would feel if you were the parent of the Asian child, the black child or the poor white child who is being made fun of in these pictures. These are the lessons that last a lifetime. Have you taken note of any offensive Halloween costumes this year? Post a comment and tell me what happened.
