Could the reason for the number of broken bone cases at the FLDS have anything to do with possible ‘severe mental retardation’?
It’s not a good idea to let retarded children drive the ‘farm tractor’.
No, the fumarase deficiency syndrome is the form of inbreeding-related retardation you’ve heard about. Those kids rarely even advance to the point of sitting up or crawling. They are certainly not driving tractors, or even helping set the table for dinner. They lie in cribs and get fed and get their diapers changed, and that’s about it for their lives.
