Most right-wing conservative religion?

[Citizen James]

The "Creativity movement" would probably be considered the most extreme socially conservative, as they are essentially neo-nazis.

In general, Dispensationalists have more or less been swept up in the neo-conservative movement.   This covers many southern Baptists, pentecostals, and similar charismatics.

In my personal experience, most Mormons I've known tend to be more along the lines of traditionalist conservatives.   Generally fairly polite and respectful of other views as well.
