The devil you know is always preferable to the devil you don't know.
100 years of being "bred" for obedience and compliance will create a group that never questions and always accepts the status quo. The women who don't "fit" leave and the ones that do fit stay and have 10 children. The FLDS gets rid of ANYONE who doesn't subjugate easily - members who "think" or "question" or "defy" are quickly shoved out. I am sure that personality wise the majority are very much followers and the "training" basically enhances this. Plus, I get the idea that IQ-Wise these folks are GENERALLY very "average" or low average - education beyond 8th grade is rare and a thirst for knowledge is PUNISHED, not encouraged. They don't even READ (there are only 10 books total approved to read), they watch no TV, no news, no movies, no DVD's - they hear no music, read no newspapers, magazines or books, they don't "create", they don't have art, nor are they exposed to any. The girls learn to garden, cook, sew, clean and care for children, the boys learn to farm and do construction. Their life as a long trail of obedience and following and working at menial, repetitive tasks. And the LEADERSHIP wants/demands it that way - they don't want followers who question them - and so they "remove" those who dissent or are smarter than the average.
I look at it and see a "Breeding Operation" - maybe a dairy farm, where girls are desired and boys are unwanted...(you only need one or two BULLS, after all). You breed selectively for the sweetest, most compliant, cooperative "high-producing" females. Soon you keep ONLY the cows that work best for your operation and you keep breeding back to the same lines to select for those same qualities. You get the cows pregnant very young and from then on you keep "milking" them until they can't produce any more. And the BOYS? Well they are used to increase your "cash flow" because they get sold out for "veal".
It just takes ONE WOMAN (or girl) from the YFZ Ranch to break the FLDS and perhaps there is still one there with the "right stuff". Even when you think you have bred very carefully for the perfect offspring, a mutation or a throw-back slips in and ruins everything. Somewhere in the FLDS history there is a smart pioneer woman with a constitution of steel and drive to push the envelope and forge new territory. A woman NOT accepting of the status quo OR the control of a man. I PRAY that that legacy lives strong in a woman from the YFZ and that she gets a revelation - not like the abominations Warren Jeffs is always blabbing about - but a REAL ONE - from GOD!
