I notice rather lot of self-righteousness and a marked inability to admit errors amongst the fundamentalists I've run into on the internet. A refusal to consider other people's positions and a tendency to invent motivations for others, too. If these attitudes carried over into personal relations then a high divorce rate would be predictable.
Also, I understand that "saddlebacking" is a term that derived from the Saddleback church. It's more than just dancing that goes on.
