Dang, there you go thinking in absolutes because you want to avoid information that goes against your arguments.
You mentioned homicide rates. They're not 0 on any of the continents you mentioned. Why are you arguing against me as though I think there's no desire to kill in the nations you mentioned?
Homicide rates are lower in some nations than others, regardless of gun laws, because of their culture. Why is this so difficult for you to understand?
This is my point. You will avoid any information that contradicts what you want to believe and then get mad when people don't live in your fantasy world.
