Arabs and Iranians have a lot of similarities.
I'm not denying this; in fact my post is motivated by a dislike of the Fox News brand of "evil a-rabs". Or the Americans that talk about "all those Arabs out there in the Middle East." who usually couldn't identify any of the countries on a map. (NOT SAYING this is Tiffany! lol It just brought the issue to mind for me.)
From what I've seen, they are quite different from typical Arabs. I know they are ethnically Persian rather than Arab. Iran has been in the news a lot during the past few years, so I've seen lots of scenes from the country.
I'm sure there's been some mixing because of geographical proximity, etc. and they do have features like dark eyes and hair, but aren't those similarities in the minority?
Isn't their religion even different? Sunni vs. Shiite Muslim? I could be wrong on this point.
