@lmrocha @freemo Voight-Kampff test, that's interesting (and a great scene.) As I recall the test was to provoke an emotional reaction to see if the subject had human-style emotions.
Anti-gunners, and other types of prohibitionists, often try to drive the argument toward emotion and away from logic and reasoned debate. And they HATE it when they run into someone who cannot be moved to emotion, and just keeps arguing the logic.
