Best of luck to him. The problem with the image of Arab Muslims in general in the US is self-inflicted. It's usually the open prejudice that more than just a few Arab Muslims show towards others, such as Jews, that causes them to be painted with a broad brush.
I've known and flown with some Arab-Americans and Iranian-Americans. Those people have made it publically very clear about which side of the fence they stand on. They stand on OUR side, and not on the side of the fanatics, Jew-haters, the limp-wristed, keep-your-mouth-shut cowards, or the substancial number of silent tacit supporters of the Islamic fanatics.
