The poster of the original article doesn't seem to be nearly as upset (as far as I can tell from his website) about atheists or agnostics as he is about other Christians who don't adopt his detailed reading of the Bible right down to the last punctuation mark.
He's probably spent so much of his life trying to kick other Christians out of the tent that all ten of his toes have been broken quite beyond recognition.
