Like the other identifiable races, Black people are in reality a collection of groups differentiated by gender, class, ethnicity, sexuality, culture, skin color, profession, and nationality-among a series of other identifiers, including biracial people who may or may not identify as Black. Each and every identifiable Black group has been subjected to what critical race theorist Kimberlé Crenshaw has called “intersectionality”—prejudice stemming from the intersections of racist ideas and other forms of bigotry, such as sexism, classism, ethnocentrism, and homophobia. For example, sexist notions of real women as weak, and racist notions of Black women as not really women, have intersected to produce the gender racism of the strong Black woman, inferior to the pinnacle of womanhood, the weak White woman. In other words, to call women as a group stupid is sexism. To call Black people as a group stupid is racism. To call Black women as a group stupid is gender racism. Such intersections have also led to articulations of class racism (demeaning the Black poor and Black elites), queer racism (demeaning Black lesbians, gays, bisexuals, and transgender people), and ethnic racism (concocting a hierarchy of Black ethnic groups), to name a few.”
