Truman Capote was a pop figure, but it wasn't until he went on David Susskind's show and had that extraordinary voice and manner that everyone could imitate, that he really took off as a figure.
When violence is real and you flinch away from it, violence does not push people to try and imitate that. Often, we shun the violence that makes us flinch, because it disturbs us. And what makes us uncomfortable and disturbs us is not often bad. What disturbs us will not make us imitate that.
