I find it interesting that they rather be called as Persians, rather than as Iranians.
One of my gifts, often is an ability to identify accents and facial features of people, we meet and link them to certain geographic areas of the world.
When the bells ring and it appear that the new person/people we are meeting is a Persian.
Then, I ask them up front if their are Persian. They usually pause, then smile and say yes. They are often highly educated and motivated people. They would handle the Islamic Threat different than we are handling it now.
