The concept of fighting back against an active shooter, terrorist, or whatever. In Euro-Poor countries you cannot do anything other than be slaughtered like a helpless lamb. Here in the United States there are countless examples of based armed citizens pulling out their CCW and smoking a criminal. But you don't see that ever happen in Europe. In Europe you just simply get your head cut off by a jihadist or acid splashed in your face or whatever, and you can do nothing but die. That is no way to live, but this is the dystopian nightmare Europe is under.
