Proof that mormons are retarded

Or at least produce mentally retarded children. A rare, severe birth defect is on the rise in an inbred polygamous community on the Utah-Arizona border, according to a doctor who has treated many of the children. Intermarriage among close relatives is producing children who have two copies of a recessive gene for a debilitating condition called fumarase deficiency. The enzyme irregularity causes severe mental retardation, epileptic seizures and other effects that often leaves children unable to take care of themselves. [...]

Tarby believes the recessive gene was introduced by one of the community's polygamist founders.

Community historian Ben Bistline said most of the community's 8,000 residents are in two major families descended from a handful of founders who settled there in the 1930s.

"Ninety percent of the community is related to one side or the other," said Bistline, a former member of the sect, the Fundamentalist Church of Jesus Christ of Latter-Day Saints.

"They claim to be the chosen people, the chosen few," Bistline said. "And their claim is they marry closely to preserve the royal bloodline, so to speak."

You mean that in-breeding is bad? Nooo!!!!! You don't say!
