microaggression
n.— «Social scientists call the event a “microaggression,” by which they mean one of those many sudden, stunning, or dispiriting transactions that mar the days of women and folks of color. Like water dripping on sandstone, they can be thought of as small acts of racism.» —by Richard Delgado, Jean Stefancic Critical Race Theory May 1, 2001. (source: Double-Tongued Dictionary)
