"Once it is demonstrated that people hopelessly addicted to some form of ancient superstition cannnot be depended on to engage in "rational thought," "

well, Riginslinger, there are three (3)...count 'em..unwarrented assumptions buried in that introduction to the obvious 'truth' that "·.it becomes difficult to convince them of anything."

1) How do you "demonstrate" any such thing?
2) How do you 'prove' that it is superstition and not 'revealed truth?
3) It is not necessarily the case that 'believers' cannot also use "rational thought"..

Again, I agree with much of the thrust of your concern, but it is so easy to overstate what you are trying to say.
