But actually, I believe the immigrants in Italy also should be allowed to carry weapons.

No great suprise there.

Those who are peaceful need to protect themselves from racists or other bad people. This way, people who prefer to avoid conflict will have the best chance of survival (because they'll get in gun fights less frequently), and those who pursue conflict will have the highest death rates (often due to fighting between one another, but also by being shot by their intended victims) -- thereby improving society in the long run.

It all sounds so rational. But I'm afraid no rationale will make the proposition "more guns = a safer world" true.

Why is the cry "He's got a gun!" an urban nightmare, no matter who it's applied to? Why do people scatter, dive for cover? Guns don't just shoot bullets, they attract bullets as well.
