Islam is an antiChristian religion, when I say this, I do not know if Mohammed was THE antiChrist but he was AN antiChrist figure. He rewrote the Judeo-Christian Bible to suit his agenda for power. He denounced the divinity of Christ and the resurrection; these 2 acts make him an antiChrist. He speaks in the name of religion, acknowledging Jesus Christ, and then leads the flock astray (billions have served him).
Islam has several "truths" that prohibit reformation/tampering with Mohammed's text.
Mohammed called himself "the last prophet". Jews await the first coming of God incarnate, Christians the second and when He comes again we should be on the same page as to who He is. Muslims have their teacher who has forbidden them to look for any other.
The one sure sign that Imam agree permits muslims to engage in a physical holy war (jihad) against the Judeo-Christians (people "of the book"), moderate muslims, and everybody else (infidel) is when a nation attempts to "suppress" Islam. Even a reformation movement as to suppressing certain aspects of Islam can be a trigger for radical muslims to go to war.
Islam itself cannot be reformed. I do not say that we can outlaw it (we have no prohibition on people believing in astrology either) but we can defang it and not permit the church sponsored violence (taking the radical clerics/mosques down as the terrorist cells they are). We can pressure Islamic nations to not discriminate against people of other faiths; no distinctions in the law between muslims, Judeo-Christians, and "everybody else"; no death sentences for muslims who convert away from Islam or people openly practicing other faiths.
The KKK is permitted to exist in America but it cannot advocate violence. It is your God given right to be stupid and reject His teachings. Come to Him through free will.
The other side of reformation can come from muslims who wake up to the fallacy that is Islam and return to the Judeo-Christian Bible (whether they choose to accept Christ as divine or man).
A hopeful comment. We might be able to defang it publically (driving the violent adherents underground) but even if that were successful it could only be done in non-muslim countries.
And how can hostile Islam be defanged with regard to its eternal threat of the destruction of Israel?
