- the rape, torture, murder, enslavement and other forms of violence these groups inflict upon people is overwhelming inflicted upon other muslims
Just a side note to throw into the discussion. In the eyes of the Jihadis (or, whatever you want to call them), those people we refer to as "muslims" they victimize are not muslims.
I have a student who grew up in mostly in Egypt and and also had some time in Turkey. He noted that Muslims, at least where he is from, classify races by behavior, and thus anyone that believes differently from them are not Muslims. Thus, when you here some talking head Muslims after events such as the recent attacks in Paris and Nigeria say that the perpetrators are not Muslim, they are probably honestly stating their beliefs. The only problem is that those that are dong the raping, pillaging, and murdering don't consider those talking heads to be Muslims either.
As a side not, just to screw with your minds, according to my student, in the eyes of the people he grew up around, there are only four races in the world: Muslims, Jews, Americans, and Somalis. Still trying to sort this one out.
