I would repectfully recommend you read The Politically Incorrect Guide to Islam (and the Crusades), by Robert Spencer. Having him as a guest on your program to discuss his book would be very helpful to restoring your credibility on the topics of Islam and The War Against Extremism. It would also better equip those (apparently few) members of your audience unfamiliar with the real Islam to defend themselves against an ancient and ruthless foe.
(A link to his site, Jihad Watch, on your 'blog wouldn't hurt either.)
I would also respectfully suggest that your reliance on "theologians" to answer the question of whether or not Christians and Muslims worship the same deity reveals the same unfamiliarity with Qur'anic Islam (as opposed to CAIRic Islam) you displayed when you gave a spokesman from that Jihadist organization a platform on your show.
It is blasphemy to try to equate Christ with Allah, and only deceit or ignorance would make such an effort. Because a counterfeit religion tries to gain acceptance by leeching onto the Faith "once for all delivered to the saints," we should accept their claims uncritically? Would you give Mormonism that consideration? Would you allow Jehovah's Witnesses the same courtesy? Why then why would you swallow whole the falsehoods of a religion that has historically slaughtered those unwilling to submit to its ideology?
Any elementary (and honest) comparison between the Qur'an and the Bible would reveal that if it is the same god Christians and Muslims worship, that god is either a liar, a weakling, or insane:
The Bible tells us our Father said of Jesus, "This is My beloved Son; listen to Him." Jesus confirmed Peter's confession of Him as the Son of God.A comparison of the two religions' founders also reveals why Christians and Muslims cannot be worshiping the same god:
The Qur'an says that anyone who says Allah has a son is an unbeliever.
Both religions' claims are mutually-exclusive. Either one is true and the other false, or the other is true and the former false, or both are false, but both cannot be true. If it is the same god, then that god is either wickedly deceitful, unable to preserve his word, or mentally unstable.
If the Bible is true, Allah is lying. If the Qur'an is true, YHWH and His Christ lie.
Jesus said, "Love your enemies."The two religions' histories also reveal they serve very different gods:
Mohammed said, "Kill the unbelievers wherever you find them."
Jesus healed the sick, raised the dead, and committed no sin.
Mohammed was a murderous, deceitful pedophile. (Lest you try to accuse me of an "extreme" position, Mohammed killed, maimed, and had assassinated thousands of people, taught and practiced "War is deceit," and consummated his marriage to his six-year-old bride when she was nine. All this is recorded in Islam's own accepted traditions).
The Church was slaughtered for centuries after its founding, "turning the world upside down" and expressing the love of Christ in word and deed.Have the courage to face Qur'anic Islam honestly and clearly. Yes, the implications of a religion whose text commands its billion-plus followers to fight against, subdue, and kill "unbelievers" is frightening, but what is the alternative? Hide our heads in the sand until we have no heads left to hide? (Beheading is commanded by Allah.)
Islam spread for centuries by slaughtering others (and it hasn't stopped).
