They normalize racism. They make racist assumptions a part of everyday life. The assumption that a black father isn’t in the picture reinforces an image of irresponsible black men that keeps them from being hired for jobs. The assumption that a Latinx woman doesn’t speak good English keeps her from a promotion. The assumption that a child of color’s parents wouldn’t have a college degree encourages guidance counselors to set lower goals for that child. The assumption that black people are “angry” prevents black people from being taken seriously when airing legitimate grievances.
