Only because people let it. There is little danger form actual terrorism, but there is massive danger from people's reactions to terrorism.
I think you underestimate the impact this type of terrorism has. The real massive danger is constantly trying to downplay it. The simple fact is, when facing an irrational enemy the last thing you can do is try to shift the blame to those who react.
No, it's not. The danger is over reacting, as history has proven time and time again. Fear is not the answer.
