Are you a hafiz? If not then I'd find it a tad, bold, to claim who is and who is not correctly interpreting their holy text (pet peeve).
With little knowledge of the contents of the Quran I'm going to guess it reflects the attitudes and mores of 7th century Arabia with the actual ideological interpretations by adherents being dependent on the material conditions of its followers. I.e. If there's political and economic stability they'll be relatively peaceable; if they're living in a bombed out third world country with rampant poverty, they will not.
