Stereotyping is impossible to avoid and even healthy.  Humans survive because of stereotypes.  We need summary judgments to function; this is the core of translating perception into thought.  The problem is when people willfully ignore signals to look past the stereotype.<p>If you think that every person you meet alone on the street in any city on the planet is equally dangerous or equally safe regardless of what you observe, prior to any actual violent behavior, either one day you&#x27;re going to get hurt, or you&#x27;re not going to visit any dangerous places.
