Lets get things straight: what this thread is on about is organised religions which impose a set of rules for living one's life. By and large, adherence to these basics (love thy neighbour as thyself is really the only one) would eliminate all wars and friction between ethnic groups.
However, there is a great and fundamental difference between Religion and Faith. Faith (for me at least) is a belief in the existence of a bountiful and merciful God who's only son (Jesus) suffered and died for us all, and will come back to claim us one day)
Unfortunatley, many groups (Catholics included)decided at a very early stage that it was necessary to make rules and regulations as to how one should follow Him, taking a leaf straight from Judaism, which became obsessed with adherence to the rules rather than seeking the truth in ones own way.
So, there are many of us about who profess a faith of some sort, but do not claim to be a partaker in any from of organised religion.
Simple adherence to the love thy neighbour rule should suffice for all, but thats a very hard thing to understand and could mean letting go of long held beliefs and prejudices.

Hope this screed hasn't bored anyone, but its a good thread and is at least thought provoking.
