K4L, in regards to your claim that JW's are the most peaceful religious community in the world, there are many, many religious groups that practice non-violence. The Quakers and Mennonites are two such Christian groups.
Additionally, ahimsa (which means "not killing") is a part of the main Indian religions. In addition to humans, it extends non-violence to animals. So, while most JW's wear and use leather and eat meat, many Jains, Hindus and Buddhists see this as violence and, in addition to refusing to make war on humans, refuse to make war on animals.
It should also be noted that JW's support the divinely-ordained wars of the bible, as well as divine war on unbelievers and their "system of things," meaning that you are not against war in and of itself. You are against man-made war. A very precarious peace, indeed.
