Dylann Roof was not silent before he murdered nine black people in their church, shooting and reloading multiple times, destroying their bodies with his white rage. He did not shout obscure or difficult to translate Latin phrases. Dylann Roof was not a blank slate or deep and nebulous well who left no written justification or explanation for his evil deeds. White racial terrorist Dylann Roof told his African-American victims why he was going to kill them. As though it was a type of forced civic duty and obligation, Roof said to his victims: “I have to do it.” He then shared his grievances: “You rape our women and you’re taking over our country and you have to go.” Then he let off a fusillade of bullets.

Nationalist and politically chauvinistic ideologies tend toward patriarchy and sexism. White nationalism is no exception. As such, Dylann Roof’s white racial terrorism is an act of violence, and one that is grounded in a particular understanding of gender: “Male” or “female” are designations of human, sexual, biological difference. “Masculine” and “feminine,” however, are social constructs that are not fixed, which change over time, and in response to particular arrangements of social and political power. Here, gender is a type of performance (in its most binary and simple form) as a given person acts “male” or “female.” And toxic masculinity is a performance that emphasizes violence, control over others, sexual aggression and a lack of emotion and vulnerability. Dylann Roof—with the guns, violence, resentment, right-wing politics and racism—is the extreme embodiment of toxic white masculinity.

The color line is not separate from gender: The two are deeply connected to one another in the United States and the West more broadly. Dylann Roof’s performance of gender involved an understanding that he should have power over and was inherently superior to people of color because of his skin color. Moreover, as understood by his racist political ideology, Dylann Roof was granted an additional claim on power and authority because he is a man. Roof's racism and sexism thus intersect in what philosophers Carol Pateman and Charles Mills have described as “racial patriarchy.” This is a system of racial domination in which people of color are subordinate to whites. It is also a relationship where white men have more power than white women. But all white people have a higher place than any person of color—either male or female. Women of color occupy the basement level of a society organized around a system of racial patriarchy.

This system, in its most unapologetic and honest form, is the dream of white nationalists.
