Actually, I'd say R/S is religiously divided between atheist materialists and a variety of, essentially, New Agers (as much as many of us might oppose that label), united only in a distaste for traditional fundamentalism. ED certainly skews 'Liberal' (i.e. Left-leaning moderate), but there's always a vocal minority of the Rand/Paul crowd. As someone else already said, a lot of the "arrogance" just comes down to adolescent posturing, and as I said a while back, DV ED is less prone to e-peen sword-fights than a lot of places on the web.
