Yeah, but I imagine for believers it's a "same difference" kind of scenario. If you worship the same God "wrong," you might as well worship a different one. Though I suppose in some Islamic theocracies, Jews and Christians enjoy significant privileges over polytheists, animists, atheists, and Zoroastrians. In Islam's earlier days Muslims were certainly much kinder to the "people of the book," until around the tenth century when Jewish and Muslim scholars began to officially declare Trinitarianism as a kind of de facto polytheism. But as time passed, even the bond between Muslims and their Jewish predecessors wold not survive the divisiveness of apocalyptic orthodox monotheism.
