We are a commune of inquiring, skeptical, politically centrist, capitalist, anglophile, traditionalist New England Yankee humans, humanoids, and animals with many interests beyond and above politics. Each of us has had a high-school education (or GED), but all had ADD so didn't pay attention very well, especially the dogs. Each one of us does "try my best to be just like I am," and none of us enjoys working for others, including for Maggie, from whom we receive neither a nickel nor a dime. Freedom from nags, cranks, government, do-gooders, control-freaks and idiots is all that we ask for.
Rev Graham is a full-blooded Christian. As such, he is likely to view Islam with alarm because of its strident anti-Christian message and because he genuinely believes that Islam diverts souls from God. He may hold a somewhat similar view of Judaism and Buddhism among others. Being a Theist, I would probably also make Rev Graham's list of those who are being diverted from God.
I am sure that, at the National Day of Prayer, Rev Graham would have acknowledged his own beliefs without insulting anyone else's.
The Founding Fathers were a motley religious crew. George Washington was careful in public to speak of Providence rather than a specific God. Thomas Jefferson did not make public professions of Christian faith and Ben Franklin -- well, yes, look him up. We've elected 4 Unitarian presidents.
As for religious groups and terror in the name of their religion -- the Latter Day Saints established a community that bordered on cultism in Utah. The Mountain Meadows massacre was a dreadful event and there were others. That part of LDS history is long over but it happened. We also had some ugly 17th-century events involving heresy charges among various Christian sects.
I just find it interesting that no one has connected the dots between Graham's being banned from speaking before the military, on the one hand, and the fact that the Comedy Central Network censored a South Park episode because it had showed images of Mohammed and the show's producers and the network had received death threats.
