David Wood just posted this video---given how often David "blasphemes" the "Prophet," he better watch this one multiple times. Of course, any criticism, even if it is based upon historical facts, Islamic sources, etc., is considered to be an "insult" to "the Prophet." This form of Islam is truly the Religion of Perpetual Outrage. It is next to impossible to reason logically with such folks. Thankfully, not all Muslims would take this fellow seriously. But why they would not is the real question.
For even if many men once boasted that they worshipped the Supreme Majesty, the Maker of heaven and earth, yet because they had no Mediator it was not possible for them truly to taste Godís mercy, and thus be persuaded that he was their Father. Accordingly, because they did not hold Christ as their Head, they possessed only a fleeting knowledge of God. From this it also came about that they at last lapsed into crass and foul superstitions and betrayed their own ignorance. So today the Turks, although they proclaim at the top of their lungs that the Creator of heaven and earth is God, still, while repudiating Christ, substitute an idol in place of the true God. - John Calvin, Institutes of the Christian Religion (Book II, Chapter VI).
