No point in engaging Prowler, or anyone else in this thread for that matter, but he's right that the old Testament is similarly violent compared to the Quran and hadith, but the important difference is that Christianity and Judaism underwent a reformation. Islam has not.
Christianity and Judaism allow "interpretation" wiggle room because the Bible consists of didactic parables. The Quran is the literal "infallible" words of Mohammad commanding you specifically on how to live.
