I worked with some Iranian engineers who immigrated to the USA.

They absolutely thought they were superior to everybody. I had to go on a business trip with an Iranian PhD who bragged about how pure his family genetics were because they marry their cousins and had been doing that for many generations.

I told him that the USA is an example of what your get when you mix many different ethnic groups, i.e., a lot of hybrid superiority.

Just look objectively at the results. Where is Iran relative to the USA?
