No idea about relative intelligence levels but there is a noticeable poor use of grammar and bad spelling from a few theists here and other forums. I'm not perfect but I see a better level of writing from non theists here, even after pointing out an error for them they usually continue to spell the word wrong (or use the wrong word). They know who they are.
I don't know if that's stupidness or sheer bloody mindedness but if someone points out an error in my writing then I make damn sure I take it on board.
