These are people that read the Bible and go completely apeshit.
I'm not talking about the Mormons, or even (mainstream) Baptists. I'm talking about these kind:
Fred Phelps, and his Westboro Baptist Church.
Chick Publications.
They are characterized by their complete and total departure from anything that Jesus actually taught, and replacing it with pure Hate.
Of course, these are only manifestations of one man's model of the world. Your mileage may vary.
