I think you used the word right winger and left winger wrong. There is no such thing as that in middle east. Those extremist are practicing a radical way of Islam in which they are very strict about their religion being that those who don't convert are infidel and should be killed. This types of people are straying from the meaning of the word jihad because they thought that violence is the answer. We can't drive out these people or eliminate them, as long as there are people who are willing to sell weapons to these kinds of people violence will continue.
