I believe their motivation for their odd beliefs is anti-science. Science's greatest accomplishment is putting a man on the moon. So being reactionary against science would make one who can't articulate his/her problem with science, want to pull down the curtain and show the wizard as what he is, a charleton.They want to do this because they feel threatened by science. Science types have accused their beliefs of being superstition for as long as there has been Science. Science has many True Believers,Science beaters and They ,like Bible beaters, are annoying.
The Nihilist Church of Galileo and later day Scientists.
Folks who think reason or common sense are synonyms for science
folks who think the Christ story is a myth , but, Galileo was REALLY crucified for his beliefs.
Folks who don't discern the diffrence between knowledge and wisdom
Folks who think the big bang theory even hints at anything that resembles an explanation for anything
Folks who are learning to speak Klingon
Folks who think they are not participating in a belief system when they use "It's a scientific Fact" like an weapon in argument and frequently are practicing blind faith in these "facts".
folks who think science can ever go that last mile and know the universe mechanically, ignoring the true mystical nature of the place


Please note I didn't mention anyone acctually validly practicing SCIENCE. Just the cult of Scientific Dogma, and also let me say that I am not a fan of the oppositions Dogma either. The western world is so dualist in thought patterns that everything gets setup as polar opposites.Science Vs. Religion, dems vs reps, us vs them. Many people just get caught up in the tides of one camp vs the other. They don't recognize the motivation behind their belief so they get into some strange places.
