the people who get upset are the people who feel threatened. christians who get upset probably aren't completely sure of their own faith. athiests, well, people who aren't mainstream get "attacked" all the itme, so are very defensive quite often.
they need to take a lesson from the villagers and learn to get along with their own lives and let it go.
can you imagine if there really were factions in our little villages that just refused to get along? they wouldn't survive.
