In the context of an entire presumed talk, conference, interview, panel, or whatever presumably about race and racism... nah not really lol. Dude only really has about a minute to respond, and he probably spent already at least 30-45 minutes about it. At some point if I ask a biologist after a discussion about biology what a biologist is, "a biologist studies biology" makes sense. If you go to an entire talk/convo/conference/whatever about a subject and still need someone to define the subject to you, idk man?
