Only fools believe ISIS gives a damn about that. ISIS declared war on the entire non-Muslim world the day it was created. That's why it was created.
Maybe true. But ISIS is a small group, hence it's quite stupid to declare war on all of Islam instead of declaring war on ISIS.
Pretending this is somehow the fault of conservatives is the ultimate idiocy and also an act of treason to your civilization.
By declaring war on all of Islam instead of declaring war on ISIS, you're doing the bidding of ISIS. Please stop.
