I know people who lived like that and I did early in my life too and the politics are intense. Women get a short shrift and if you are in any way unusual you better move out. Someone I know moved countries so that his parents would not just take a bus or train and land up at their doorstep. Families can be toxic, large families more often so. The amount of abuse brushed under the carpet in order to keep the image of a large, happy family in front of outsiders can be staggering. Think of all the stories that come out of FLDS compounds.
