It isn't apologism to claim that its bizarre to talk about converting an enemy under the pain of genocide. Then again maybe ISIS must be annihilated but we have never annihilated anyone that are not Native Americans yet. If that's not enough, they brought conversion in as a sole condition of surrender. Maybe it would be cool if we were governed by Octavian or Richard II. But this isn't 1205 AD or 5 AD.
This. And "convert them or kill them" implies that the problem isn't their violence, but that they believe in the wrong god.
