This is the general strategy. Watch how it works when Yahya addresses the kidnapping, torture, rape, and forced conversion of nearly three hundred Nigerian schoolgirls by Boko Haram.
Did you catch that? Islam condemns forced conversion (which it doesn't), but (a) the reports may be false propaganda against Muslims, (b) Boko Haram is only doing it to defend their Muslim brothers, and (c) critics of Islam need to keep their mouths shut about this.
Apparently, Yahya knows that it simply won't be effective to come right out and defend Boko Haram's actions, so he prefers a strategy taken straight from the likes of CAIR: defend terrorists indirectly by blaming infidels and demonizing critics.
Interestingly, by saying that Islam doesn't allow forced conversions, Yahya has condemned Muhammad and his companions. Consider the following description of Muhammad's mission by Muhammad's closest companion, Abu Bakr (who was warning apostates that they would be killed if they refused to return to Islam):
Al-Tabari, Volume 10, p. 55—Abu Bakr to the Apostates: . . . “Verily God, may He be exalted, sent Muhammad with His truth to His creation as a bearer of good tidings and as a warner and as one calling [others] to God, with His permission, and as a light-bringing lamp, so that he might warn [all] who live, and so that the saying against the unbelievers might be fulfilled. So God guided with the truth whoever responded to Him, and the Apostle of God, with His permission, struck whoever turned his back to Him until he came to Islam, willingly or grudgingly.”Notice the last part. Muhammad "struck whoever turned his back" to Allah until they came to Islam "willingly or grudgingly." That is, people were going to come to Islam whether they wanted to or not.
This is what Yahya assures us has nothing to do with Islam. Does Yahya expect us to believe he's a higher authority on Islam than Muhammad and Abu Bakr?
