I also would like to add on this one... most Christians are actually non-violent simply because they are not the type who strictly complies with the Bible standards particularly in the "Old Testament", noting that most of them, particularly among the bigger denominations, never cares to read the bible, while those who read adjusted themselves by ignoring some Bible standards in order to comply with "real existing laws".
A Personal Opinion
Riggio has a point on this one, religion serves as guide to religious people. However, religion-driven people think of it as more than just a belief system - which is subjective to a group. They thought of it as if it's God's command. And this kind of primitive mentality (brought about by an evolutionary process), is more likely to cause disaster. People has to adapt to an ever changing society and sometimes, dogmas prevent it from happening. But who goes to say that religion does not bring anything good (progress for that matter)? It does, it's just that it wouldn't be right if we let it control everything, I mean, who are the pastors, the clergy, or the Imams/Rabbis who decide for the group anyway? Aren't they men also? Surely they are not gods and they are also prone to errors, along with their scriptures, which was written by primitive men a long time ago.
