Fighting superstition is hard work
What’s the harm in a little superstition? Ask all the people who listened to an energy peddling “holy man” and ended up worm food. These were folks who received advanced warning from serious scientists, and still chose to believe a man who managed to convince himself he could speak directly to the spirit of the volcano.
You also have to love how “Islamic” Indonesians are. It’s obvious elements of their polytheism are still alive and well. Jihad, anyone?
