You know when they send people door to door to try to convert you? The church knows that they have no chance of converting you. That's not the point of sending these people out. The point is to train them to use the most annoying of tactics on you so you'll be visibly aggravated with them. To get doors slammed in these people's faces over and over again. The point is to teach the people going door to door that the world hates them, and that the only safe place for them is back at church, among other Jehovah's Witnesses.
