"What difference does it make" - hmmm, shades of hillary.  

It makes a huge difference to name who the enemy is. Ask Hillary- Oh wait,  she named  and blamed an innocent film maker instead of naming the mass murdering enemy, islamist terrorists.

The large difference between "radical Muslims" and "radical Christians" is one commits mass murders by attack on innocents, including children, and the other one often holes up in some compound with adult people who have willingly joined them.
