McGrath, here in the states we have this phenomenon known as evangelical Christians. They may be from a number Protestant sects, but those who are usually working the extreme right wing political agenda are also referred to as fundamentalist Christians. The Protestant sect that group of so-called Christians are usually affiliated with is Southern Baptist. Because of the history of the US apartheid system, there are black Southern Baptists sects, and white Southern Baptists sects. Is that confusing enough for you?

There is no true equivalent to the Southern Baptist Protestant sect anywhere else in the world, that I am aware of. It is uniquely American. Their religious roots are mostly Calvinist from what I can tell, but I don't know much about the history of the Southern Baptist religion. Maybe someone else can comment upon it.
