Social loses.
Social winners.
Social run of the mill.
Islam is all about violence, and it has a never ending supply available for everyone who embraces it.
Social losers in Islamic countries do not have a way of lashing out at society because they would be imprisoned or killed if they took out their frustrations on the Muslims around them. But when they come to Western nations they have a large population of victims. They can take out their frustrations on the European or American population and still be heroes to many people in their communities. For the first time in their lives they will have fame, and approval.
