You picked up on that, did you? I also detected a distinct disdain for the true believer, but I thought the presentation was quite civil. Anyone who attempts to take every word of any religious text as completely and literally true will go mad (or already is).
Flame away.
Hint: there have been so many interpretations over the centuries as to what "completely and literally true" means, that I doubt if you could find any random group of believers to agree on any major issue.
Propaganda, in its best form, succeeds in its pretense.
