The Pope has apologized--for being right. Why won't moderate Muslims step up and say that the apology was NOT necessary, that the violent and ignorant reactions of their co-religionists were what was wrong.
Those who fear Reason the most will exhibit the most vile responses to rational discourse. Dialogue is what they DON'T want.
Eventually, the world will be forced to discern who the "they" are. Better the Muslim community, the Ummah, should accomplish this first, and do so publicly, and deal with it.
