I wouldn't say that atheists are a "small minority" in my community. (I live in Canada.)

Ah, then I apologize. When I see the phrase "evangelical Christian community," I immediately think of the U.S.

I think that seeing the hold religion has on much of the world, even if it's outside one's own country, could still engender the behavior I described in the first paragraph above. However, it probably is more related to my latter point.
