Exactly, saying Mohammed is a "False Prohpet" isn't "intolerance", it's fundamentally what all Judeo-Christians believe. Christians are fundamentally Jews by religion (Christ was a Rabbi and taught Jewish Law) - the original "Christians" were Jewish by both blood and religion. Essentially, Christians are Jews (by religion - some by both religion and blood) who believe Christ was the Messiah (Messiah is the Jewish term for "Annoited One", which is precisely what Christ means in Greek - many early Christian Bibles were written in Greek). In Rome, prior to Constantine, the Romans made no distinction between followers of Christ and "Orthodox Jews" (Jews who believed Christ was a Rabbi but not the Messiah) as being Jewish by faith (celebrating any religious faith inside Rome was a criminal offense punishable by death in ancient Rome prior to Constantine - and the Romans put many followers of Christ and Orthodox Jews to death in the Lions Den, among other ways, for celebrating the Jewish Faith inside Rome's walls). Saying that a couple billion people are "intolerant" for believing Mohammad is a "False Prophet" is ridiculous.
