Even a lot of JWs hate preaching. I can understand, because they have nothing to say. They don't read the Bible, they don't know what they're talking about, they can't answer any questions. They're going out and telling people what to believe, when they are not qualified. It's intimidating, as if throwing a 4th-grader into the job of brain surgeon, especially with all the hype about it being a "life-saving work". That's a lot of pressure on someone who is completely clueless about what they're doing.
Moses and Jeremiah were reluctant to speak, because they didn't feel qualified. When Jehovah gave them his message, they preached with boldness. Once they had something to say, they became confident. Even JWs understand they can't go to someone's door with a bunch of arbitrary decrees from a publishing company. They know what they're supposed to believe, but the vast majority of JWs have no clue why and can't back up hardly any of what they believe with any reputable or respected source.
The arrogance of some elders and pioneers is obvious, in the ministry. They just spout JW opinion as if the householder is supposed to either already know it or blindly agree with it. No scripture, no proof, just their arbitrary parroting of some old man's opinion. Then, when the person at the door doesn't give a toss about what some magazine says they're supposed to believe, the elder or pioneer feels embarrassed, because they believe they are supposed to be uber-preacher, but nobody cares about what they have to say. So, they call the person names on the way back to the car.
A good man brings forth good out of the good treasure of his heart, but a wicked man brings forth what is wicked out of his wicked [treasure]; for out of the heart’s abundance his mouth speaks. - Luke 6:45
