A man comes to your door saying he is a salesman for such-and-such company. He is charming and friendly, and speaks in a familiar manner. He is selling you something you always wanted, something you always needed, and could only dream about. You buy it, thanking him profusely for the opportunity. He leaves. You go inside and open the box, and it is empty. When you try to take it to the store for a refund, they tell you that they don’t have door-to-door salesmen, and the man who came to your house was not their employee. Then you are arrested for trying to defraud the store.
This is the story of the Facebook jihadi ideologues and their victims in a nutshell.
