The graph Theijsmeijer posted breaks racist math down into two categories, "Overt White Supremacy" which includes using the n-word while doing math. The second is "Covert White Supremacy" which includes "2+2=4," along with "Assuming math is neutral," "Standardized testing," and "Dismissing alternative algorithms."
