Answer:
The answer is yes. Melville is really criticizing the Christian Missionaries.
Step-by-step explanation:
Because he uses many biblical, scientific, and mythological themes to built his story. The lighting -rod man is a representation of the missionares, while the narrator represents Melville beliefs. The center idea of the story is that the christianism convertion is destroying the cultures, values, and customs established before. The convertion is not about real spiritually, but about imposing the missionaries way of living. The narrator tries to dissuade his neighbors from believing in the lightining rod man, Melville believes in a God full of love and not in a God or religion imposed by fear.
