"It is ... fear [of difference] that has lead to the pathologizing of 
nearly every normal human behavior from grief (depression) to discussing 
an illness (obsession) to fearing loss of income due to a recession 
(anxiety) to an asthmatic walking around someone wearing a strong 
perfume that is triggering an attack (antisocial personality disorder)."
