The more things change...

Arabs are 75% inbred. This may or may not be true.

I don't know that Arabs existed before Abraham and Hagar, that Iraqi slash Egyptian mix. But it makes sense. Abraham and Sarah were uncle and niece. Both Isaac and Jacob went back to their near relatives for spouses.

So even though God brought Abram out of Iraq, mysticism to monotheism, the human side remains the same. You can take the Iraqi out of Iraq, but tradition is a part of makeup not conversion.

Abraham's beliefs were converted to Christianity, but his descendants maintained their ways. They felt more comfortable marrying their own kind, which meant incest and therefore inbreeding. That's racist and deviant both simultaneously. Thus ends the lesson.
