Obviously those Muslims haven't studied the Koran with their imams. Tell them to go study.

Do you know that NO imam is viewed as a reliable translator of the Koran in Sunni Islam, and in Shia Islam, there are sharp divisions among ayatollahs as to what any verses mean? There is NO one source in Islam that has the "correct" or "widely accepted" view of the Koran. That is precisely why the Wahabbists have gained such currency---because their interpretation is "as good" as anyone else's.
That also means there are millions (billions?) of Muslims who absolutely do NOT think that the "jihad" (struggle) called for is military or political but personal.
I don't think they are interpreting the Koran correctly but that's irrelevant and immaterial: all that is important is how THEY interpret it.
