If the “closed country” causes defects and mentally handicapped children, how did mankind or any other species ever flourish? I am thinking that there are plenty of Icelanders in that country to marry and have diversity of DNA, and something is wrong the the theory of evolution.
As seen in islamic countries and now England, Asians as they call them inbreed for centuries, and represent 9% of the population and 35% of infant mortality due to birth defects related to inbreeding. They use religiously allowed sex slaves and kidnapping to enhance the DNA gene pool. Few if any studies in islamic majority countries on the effects of inbreeding with first cousins.
Iceland: land of 300,000 inbred blondes.
They now have an anti-incest app. Check it out.
Icies didn’t like it in WWII when the Allies beat the Nazis to the island to set up a base.
Now this. F’em.
