the Name of God

I hear it said often that the God of Islam is the same God Jews and Christians worship. Yet a translation of the Bible was recently condemned by Moslems because the name of God was rendered Allah. Are they saying that their deity is not the same God as that of the Old & New Testaments? I really strive to be tolerant of all faiths, but I find that tolerance isn't always a two-way street. Most fundamentalists (regardless of their specific label) seem to be more interested in being correct than being loving. They're hard to love because they reject our acceptance. Well, we still need to reach out to everyone, even if they don't reach back.
