The main point I will make about all of this is that if there's a microaggression.... I need to clarify, in case people don't understand this, that a “microaggression” doesn't mean it's small. All it means is that it happens in small interactions.
When you talk about systemic racism, you talk about it happening on a large scale, with big statistical analyses. With microaggressions, the examinations are more interactive and small-scale. Microaggressions are still really impactful, but they're happening within people's conversations. For example, when somebody hears that “these are the dirty 30 countries” or “people from here are usually liars and cheaters”, the person on the receiving end who is from one of those countries is impacted, because now you are offending them as well. It also shows that you have a bias. You have a feeling towards these people. When you're then assessing the application, how can you tell me that this feeling is not somehow being incorporated into your decision-making? That's why microaggressions are important to consider.
Also, in my studies and my research, I have spoken to respondents who spoke about microaggressions that took place 10 or 15 years ago as if they happened yesterday. The impact of microaggressions is actually quite big and long-lasting.
