I have seen many articles in favor of the idea that Islamic terrorism is not that dangerous compared to other types, like separatism. Like this. Many mention an FBI study which shows data only until 2005.
But my question is not about the number of acts of terrorism carried out. It is about how many people each type of separatism kills or injures. I could not find any detailed overviews that show comparisons of how many people were victims to islamic bombing, separatist attacks, etc. Globally, or in USA, or in EU. How many people die worldwide and in developed countries from islamic acts of terrorism compared to non-islamic one?
I'm asking this because many people say: "yes, only 6% of terrorist attacks are Muslim and religiously motivated. But these attacks take many lives at once, while all these 94% of other attacks barely leave any victims. Therefore, islamic terrorism is more dangerous than acts of terrorism carried out by Jewish groups or separatists." Is there any comprehensive proof to debunk this myth, provided it is indeed a myth?
