First, way to go Missouri for trying to own your stuff and respond appropriately. This is a good read, and more evidence of problems across the academy. I don’t expect my colleagues who are part of the dominant culture (however that manifests in your space) to always understand, but you can try. This stuff is real, and has real impacts. I’m reading Whistling Vivaldi by Claude M. Steele now, pick it up – it’s a good one. It will also provide more evidence to the reality and impact of stereotype threat and how it affects us all.
It may be worth noting this line as an example: “I have to stop and think sometimes, ‘Are they being racist? Or, is that just how they act? Or, are they just not being friendly because they’re having a bad day?'” This is one of many Black/Brown taxes. It’s a tax others pay too depending on their many identities. While you’re asking that question, you’re not focusing on your studies, success, or other things we all think about and have to manage psychologically. This is why we have to do what we can, all of us, to create safe, accepting and welcoming spaces – particularly on college campuses.
