The Bible Belt
From Utah, a correspondent for The Economist relates that
Ironically, one of the worst places [for Mormon missonaries] to be sent on a mission is the American Bible belt, says another of the students: “People there have had guns pulled on them or dogs set on them.”
Think about that. Of all the many places in the world to which the Mormons send missionaries, the one of most violently hostile religious cultures they venture into is the American South.
(Actually, are there any places to which the LDS does not send missionaries? As bad as the South may be, I feel pretty certain that there are some Muslim countries which would be much more dangerous for missionaries from America.)
“Bible Belt” is not the same as “the South”, first of all. Also, I assume the Mormon missionaries rotting in Chinese prisons would dispute that Indiana is worse. Or the ones who need cover stories to enter Indonesia. Or Saudi Arabia. In both nations (especially Saudi) they are subject to death via Shari’a.
