I don't think people are "terrified" of being preached at just weary and frustrated. You must admit it is tempting to take out all of our frustrations with saturday morning, doorknockering, get us out of bed while we are bleary eyed and cranky, gone before we think of a suitable comeback, door to door, bright eyed, bushy tailed cultists on a "mission", on the people who say they are friends and try to preach to us on an Internet forum.
