Take a glance at the front page
of Stewart's site, it will help to dissuade you from believing that anything he writes is rational. The man has such an overwhelming reservoir of hatred within him that it's scary. LBK compared him to Jack Chick - not a bad comparison - but he even hates Jack Chick (see link well down on the left side of the front page).
His only real heroes are the King James Bible and Billy Sunday, a turn of the 20th century preacher who was very well-known in his day. The funny thing about it is that, though Sunday was an evangelical who subscribed to a number of fundamentalist beliefs, he'd have been horrified by Stewart's website and likely by Stewart using him as support for his extreme beliefs.
Although, unlike the Reverend Billy Graham, Sunday was much more a fundamentalist, he routinely exhibited some of the same characteristics for which Dr Graham is notable and which were rare among the many hard-line Protestant preachers of his era. He declined to denounce other faiths (including Catholicism, which was the favorite target of Protestant preachers of that time) and he sent interest cards filled out by attendees at his revivals to the church with which they indicated themselves to be already affiliated (contrary to the usual practice of such preachers to use the contact info to create a faith community of their own). All in all, though a character and someone whose theology we'd find wrong-headed in most respects, Sunday stands out, in many ways, as a religious moderate among the circuit preachers of his time - a far cry from Mr Stewart, an extremist of the nth degree - who I think professes to be a non-denominational Baptist of some ilk - though it's been hard to tell over the years.
Bottom line, the whole focus of his writing style is to delude one into thinking that they are wrong in what they believe versus what he believes. Sprinkle a bit of what seems like reasonable theological thought among the extremist points of view and, pretty soon, you start to focus on the former and your eyes glide over the latter. Walk away and don't look back.
