text: "Why did the writer chose the offensive adjectives "neuroticism" and "agreeableness" to make her point? "
  
  Because those are the the scientific terms used in psychology.
  
  "Neuroticism is one of the Big Five higher-order personality traits in the study of psychology. Individuals who score high on neuroticism are more likely than average to be moody and to experience such feelings as anxiety, worry, fear, anger, frustration, envy, jealousy, guilt, depressed mood, and loneliness."
  
  "Agreeableness is a personality trait manifesting itself in individual behavioral characteristics that are perceived as kind, sympathetic, cooperative, warm, and considerate."
