Race is a social construct with an arbitrary and elastic hierarchy. The only static element is that people deemed “Black” exist at the bottom. American University’s Antiracist Praxis subject guide defines anti-Blackness as “specific forms of racism contingent upon or cast through the denigration, disenfranchisement, and disavowal of people racialized as Black.” And anti-Blackness is atmospheric — felt everywhere, but usually only seen if you know what you’re looking for.
