You see, you're completely missing DOC's inferred point. I'm certainly not a fan either, which is why I, too, don't care about his religiosity. It's only if you are a fan that the question could become relevant.
Southwind17, have you familiarized yourself with DOC's other threads. He tries to sell Christianity, as I mentioned, through the logical fallacy of argument from authority. To date, he's started threads on the underlying (and evidently very surprising [to him] ) Christian beliefs of Leif Ericson, Christopher Columbus, Thomas Jefferson, the founders of all the nation's universities, and now Elvis.
I'd say he started off on the historical firsts to set foot in North America (Ericson and Columbus), figuring that would convince us. Then he went to Jefferson, since he's taken by many to be the great philosophizer of the founding fathers. Having run head-on into people who knew a lot more about Jefferson than he does, he then went to our achilles heel - education, figuring we'd surely crumble when we realized that our major institutions of higher learning were originally founded with religious underpinnings. (Gasp! What a surprise! I'd have never thunk it! In 18th and 19th century heavily Christian America universities were founded on Christian principles? I'm shocked! Shocked, I tell you!)
Now, we're evidently incapable of grasping the first explorers, founding fathers or higher education..... So we're off to Elvis. When that doesn't work? Who knows? Since we seem to be heading into popular culture and he keeps lowering the target, I'm reckoning he's going to post on the Christian beliefs of Charlie O'Connell.(*)
His approach reminds me of my first day in school in Tulsa, having arrived mid-year from New Orleans via Memphis. Some kid leaned over to me to chat, and the first words out of his mouth were, "You know, Oklahoma's a famous state?" Uhhh, yeah, I've actually heard of all 50 of them for one reason or another.
(*) 5 cents for the obscure reference. Admit it if you had to Google.
ETA: I see you've already answered my opening question. I make it a habit before attacking or defending anyone to check some of their posts, and particularly the threads they've started. But that's just me - YMMV.
