My experience with Southern Baptist religion -- grew up around them and had an ex-Southern Baptist dad -- is that they have some sort of beef with MOST religious. The further away from Southern Baptist ideology the other religion is, the more they hate it. Roman Catholics, Mormons, and Jews are especially hated, but Protestants are tolerated as merely misguided. My dad dropped the church by the 1950s, yet the culture was so ingrained that was still suspicious of the Mormon family that moved in next door to us in the late 1980s. It's probably going to be difficult for Romney overcome the attitudes of that culture.

Note to everyone: Please do not mistake this comment as sympathy for Mittens.
