Look at this part specifically. What Inglis is trying to say is that many people in South Carolina do not consider Mormons part of the Christian Faith. He's rightfully asserting that if Romney claimed to be a christian, the Evanfascist pastors would be in an uproar about it. He's right, South Carolinians generally do not have a very positive opinion of Mormonism. He's attempting to give Romney advice.
And about my knowledge of Mormonism, I generally don't know very much and don't care very much. All I know that it's pretty recently that Mormons wanted to consider themselves part of the Christian faith. Smith certainly didn't consider himself a Christian.
