How do we explain, then, most of the recent violence has been Muslim against Muslim (or Arab against Arab)?
I believe that the Islamofascists justify terrorist acts against other Muslims when the Muslims work with or assist the 'infidel' in any way. This, in their view, renders them 'unclean' and a valid terror target.
This is why many bombings and attacks have been against Iraqi police stations and Iraqi security personnel....they are viewed as 'traitors to Islam'.
