 They're completely clueless. A few years ago, I was speaking with a friend who had taken it upon himself to distribute Bible tracts and other Christian materials in his neighborhood. He'd go door to door leaving the materials on the doors of homes. He told me that it was rare to ever actually speak to anyone. He just dropped off the literature and went on to the next house. But the occupants of one house in particular were very unfriendly to him and actually called the police on him.
