Common-enemy identity politics, when combined with microaggression theory, produces a call-out culture in which almost anything one says or does could result in a public shaming. This can engender a sense of “walking on eggshells,” and it teaches students habits of self-censorship. Call-out cultures are detrimental to students’ education and bad for their mental health. Call-out cultures and us-versus-them thinking are incompatible with the educational and research missions of universities, which require free inquiry, dissent, evidence-based argument, and intellectual honesty.
