I think that its coming from a perspective that is not him. A white person perspective, or at least from a discrimination stand point. I think MCs can jump out of their skins. Or at least from a third person perspective. Isn't Common a muslim? Also he could like that these Arabs that are trying to live the American dream the white way, not the Muslim way, are not true Arabs so they are "AY-arabs." Like Uncle Toms. Or he could be racist. I don't know. He is a smart rapper who have a experience with this "AY-arab" thing then we think.
