We share our theorizing about a common statement regarding a math person that is often perceived as innocuous in society. More specifically, we are referring to people's responses when an individual shares that they are studying mathematics, such as "I have always hated math" and "Oh, you must be so smart." We draw on the notions of "marked category, narratives, dehumanization," and "microaggression." We use these theoretical constructs to argue that people's responses are an instantiation of mathematics as a marked category and that they function as microaggressions, especially for minoritized students who are multiply marked. Moreover, due to their prevalence, they can contribute to students' active choice of not doing mathematics in order to prioritize their humanity. Our report further highlights the importance of mathematical microaffirmations and the development of sub-communities within mathematics. [For the complete proceedings, see ED658295.]
