Making this about their religion gives them legitimacy to claim that the conflict is about religion. This isn't taking place in America. It's occurring in a place with massive support for Sharia Law. These are areas where the populations are full Islamic fundamentalists. Why would we want to lump the entire population into a homogeneous group of baddies? Why should we insinuate that we want to fight them all? It doesn't help us; it's ammunition that they can use to recruit more Islamic fundamentalist to fight against us. It helps the terrorists. Think about that, conflating them with Islam aids and abets the terrorists.
