I don't think so. People just confuse middle eastern and mexican all of the time. My husband hates when people ask if he's Arabic, because he's Mexican. It Happens to two other Latino guys at my shop as well.
Hahahaha middle easterners, Hispanics, Indians, and anyone with brown skin; we tend to look very similar! When I was a kid I had darker skin (I played out in the sun a lot so I was this ugly burnt child) everyone thought I was Mexican!
