Bit silly to turn it into a theological discussion. The reality is that people have different interpretations of Islam, if you're completely unaware that there are sections of the Quoran that Islamists use to justify violence then the other poster can provide you with some commonly cited passages... I'm sure you can then explain that they mean something different because of [reasons]... It is all a bit pointless if you're happy to acknowledge that other Muslims have a different interpretation.
