It already is a religious war from the radicals perspective. You seem to think that keeping quiet about it will make it not be so.
Of course I NEVER said we should keep quiet about terrorism or Jihadist nut cases.
These people should be locked up or removed from this earth immediately.
What I'm against is inciting wars against entire religions.
While I agree with your sentiment, we already have the religious war because that is what they want.
I'm not saying we are starting it or should start it, merely that we can't ignore that to those who are on the other side believe it is a religious war and so it is.
The only way to stop it is to face it for what it is and win it.
