I don't know if the author thinks they are barbarians, but he does say their beliefs "are almost certainly incorrect." I will give him a few objectivity points for including the word "almost," but he follows the typical modern assumptions by using the word "certainly." The beliefs are also described as "non-falsifiable", which means they do not fit Popper's basic scientific principle, which only means that the beliefs cannot be verified using the scientific method (according to Popper), but that does not mean they are incorrect.
