People standing up for themselves and protecting their family against the victimization of an angry mob has always been a deeply popular narrative in the collective unconscious of the American public.
It's in Huckleberry Finn when the man steps out his front door to fire a warning shot at the mob he berates as cowards (because they are). It's why we suddenly sympathize with the Monster in Mary Shelley's Frankenstein when the mob shows up with torches and pitchforks. It's why Liam Neeson got to make Taken three times despite it being interesting only once.
It's a popular narrative...because despite the attempts to spin it, one man defending what is his against the many looks brave.
