Something to chew on . . .
I read this article about Cousin Marriage and Democracy in Iraqwhen it was linked from National Review Online a couple of months ago. I draw your attention to it now. Very interesting hypothesis. When I was in Egypt on a training exercise, we got one day to take a bus tour of the pyramids. The tour guide told us about himself and mentioned that he was married to his cousin and that it is common in the Middle East, though not so much in the West. Interesting . . .
