This is a repost because the other thread got derailed by falsehoods. The following is why Islam is such an unstable religion: *Quran believed to contain revelations from God *Revelations contradict each other, so Muslims are supposed to follow the most recent one, since God's word is law. *Revelations are not sorted in chronological order or dated. *any "revelation" can be used to justify violence. So really, what ISIS is doing, is not Islam extremism, it follows the Quran. The same cannot be said for Christianity and the New Testament. (the old testament is more relevant to Jewish faith, when Jesus came, he corrected the Old Testament's version of God as well as the beliefs it taught.) Violence caused by Christians is violence caused by those who did not align themselves with Christ's message of love. They suspended their religious beliefs.
