Anti-authoritarians question whether an authority is a legitimate one before taking that authority seriously. Evaluating the legitimacy of authorities includes assessing whether or not authorities actually know what they are talking about, are honest, and care about those people who are respecting their authority. And when anti-authoritarians assess an authority to be illegitimate, they challenge and resist that authority—sometimes aggressively and sometimes passive-aggressively, sometimes wisely and sometimes not.
Some activists lament how few anti-authoritarians there appear to be in the United States. One reason could be that many natural anti-authoritarians are now psychopathologized and medicated before they achieve political consciousness of society’s most oppressive authorities.
Albert Einstein, as a youth, would have likely received an ADHD diagnosis, and maybe an ODD one as well. Albert didn't pay attention to his teachers, failed his college entrance examinations twice, and had difficulty holding jobs. However, Einstein biographer Ronald Clark (Einstein: The Life and Times) asserts that Albert's problems did not stem from attention deficits but rather from his hatred of authoritarian, Prussian discipline in his schools. Einstein said, “The teachers in the elementary school appeared to me like sergeants and in the Gymnasium the teachers were like lieutenants.” At age 13, Einstein read Kant's difficult Critique of Pure Reason—because he was interested in it. Clark also tells us Einstein refused to prepare himself for his college admissions as a rebellion against his father’s “unbearable” path of a “practical profession.” After he did enter college, one professor told Einstein, “You have one fault; one can’t tell you anything.” The very characteristics of Einstein that upset authorities so much were exactly the ones that allowed him to excel.
