Do you agree with Family Guy's characterization of religion (see description)

[Redalgo]

There have always been conflicts between human beings. Our beliefs about the sacred are but a sub-component of the sum of things that comprise cultures.  People may get along fine without religion but they can also get along fine with it, as well. Likewise, plenty of folks have killed each other over religious beliefs but certainly have killed for many other reasons which do not in any way pertain to such beliefs. Although some belief systems regarding the sacred certainly appear more dogmatic, hierarchical, intolerant, and so forth than others - and I reckon those tendencies can make a belief system have detrimental effects on a society - I would say the condition itself of a person being religious or non-religious is not at all a reliable indicator of how peacefully they can (or are willing to) coexist with those with whom they disagree.
