The OP said nothing about giving him a racist gimmick.
The majority of crowds are far too eager to get involved with casual racism and the promotion of distrust towards Arabs considering the recent climate, I don't see the benefit to Sandow or WWE to perpetuate this ongoing xenophobia stereotype, I wasn't even around for it but why create ANOTHER Muhammad Hassan? It doesnt matter what they do with him, he will be pigeon holed with a gimmick like that sadly due to the political climate we live in and which would also render his career path fairly rigid even if WWE tried to make him likable.
He's also from Massachussets so he may be part Arab by blood but he is an American by birth.
I hope Sandow will be able to pull his gimmick off on full base, he reminds me too much of ADR right now, cutting the same (good) promo week after week during his debut, giving the fans a lot of expectations which may ultimately lead to disinterest after a while. So far, he did a great job though.
