Let us not confuse the two cultures with the two religions. As far as the cultures go, the Arabs are still in the era of barbarism while the West has progressed. To pan Michael Savage for pointing out the similarities in the religious angle is incorrect. Savage is one of the more independent voices in the media.
Savage fails to point out that whereas Judaism and Christianity are progressive revelations, where God reveals himself in the travails of his Elect, Islam remains in the mode of Joshua, the prophet and general. Allah is a despot; Christ is a servant. Allah is merciful and compassionate, but only to those who submit. But he does not enter covenant with his people, he does not suffer for them. Christ is the first-born; he leads from the front and places himself in peril. Allah stands beyond the horizon.
Your explanation might pass in a college-level comparative religions course taught by a liberal, but Jesus Christ and Mohammed were two different people.
That is crucial.
(Yes, pun intended.)
