Islamic State is no exception:
And the unwillingness to look in the mirror is hardly limited to groups or movements. Your group or philosophy may be nuts from my point of view, but my group or philosophy remains gilded and serene. It's as if the vampires had ordered all mirrors destroyed and the order was carried out.Fearing [Mosul, Iraq] might simply empty of civilians, or that fleeing residents may join the fight against them, the Islamic State extremists are imposing tough measures to prevent people from leaving their territory.
Who is not an exceptionalist?
