The language of pathology, mental illness, madness, disease, and disability, has long been used to reinforce other existing structural oppressions like racism, classism, sexism, heterosexism, binarism, cissexism, and ableism. And it is most disheartening when those who purport to work toward dismantling those systems still use ableism as metaphor. Ableist metaphor is all-pervasive in public discourse, academia, grassroots organizing, and left-leaning movements as well as in conservative, neoliberal, and nationalist movements. It draws on the language of disability to characterize, denigrate, attack, rhetoricize, and politicize—and it does so based on the presumption that deviation from typical thought, movement, emotional processing, communication, bodily/mental functioning, learning, remembering, sensing is evidence of defect, deficiency, disorder, and ultimately, moral failure.
To use psychopathy as the lens through which one views either systemic or individual violence is to reinforce the structural power of the medical-industrial complex at the expense of disabled people, poor people, and people of color.
My advice: Be precise in your language and say that oppressive structures are violent and manipulative. Say that those who abuse their structural positions of power act with reckless disregard for other human beings. Say that they are callous and unabashedly wielding the power that comes with their privilege.
