Sorry bro, I can't agree with that.
There is one "religion" that disguises itself as other religions to conduct its evil doctrine. It's the "religion" of the "lower case g" god of this world.
We"re looking at the war/hate mania from different angles Bro, I'm not suggesting that people living in Catholic dominated Countries are better or less violent.
I have lived amongst people who have come from most Country, and was basicly comparing Aussies many of whom rush to join the army and put up their age to be accepted in the army, with mainly Italians, friends have told me that their Fathers used run away mainly to Switzland to avoid been consprited.
Perhaps some Catholic Countries mainly South America take out their anger through revolutions instead of running off to war.
