"I'm not aware of any definitive statistice, but I think the overwhelming majority of Arabs in America are Christian."
I may have missed it, so correct me if I did. But I can't seem to recall a large outporing of public support from the large "Christian-Arab" population here in America.
As an distinct, identifiable community, I'm not sure you should expect a reaction from middle eastern Christians any different than any other Americans. They don't seem to have a distinct voice, and are frequently caught up in the "statistics" of groups like CAIR.
