Personally, I wouldn't want to be friends with an anti. If I am in a situation where me and my friend are attacked, I'd rather have my friend be at-worst a non-carrier who is willing to let me defend myself. I wouldn't want to be hanging out with someone who would beg me to comply with whatever demands my assailants had without conflict.
Cal-Guns, you bring up some good points. However, here's what happens if you make guns illegal: less criminals will have guns to commit crimes, and no law-abiding citizens will have guns to defend themselves. Even if they don't have guns, if there's more of them and they're bigger than me, they're going to win.
The homicide rate was per capita, not overall.
You also bring up the more guns, the more crimes that will be commited with guns. What about crimes that aren't? Do they go up or down? Statistics which look at all countries, and not just cherry pick, say it doesn't make much difference. It also depends on what a crime is. Like Old Gold brought up, in the US, disagreeing with the government isn't a crime punishible by death - it's encouraged in the constitution. However, in Germany 1939, it was apparently a violent crime to be Jewish. Once that went into effect, I'd say the amount of crime in Germany went up a smeg-ton.
As to a gun letting you kill someone from far away, from my understanding most murders - even with guns - happen in close quarters. The exceptions I see are snipers, drive-by shootings, and mass shootings. It would be just as easy in most cases of a robbery, mugging, or home invasion, for the perp to use a knife or blunt instrument, especially if they know that a law-abiding citizen will not be armed.
The famous "that's not a knife" scene from Crocodile Dundee just popped into my head.
ETA, posted while I was writing:
Its not about blaming the guns for the murder. The gun gives people increased ability to kill. Without that increased ability, its quite possible that they wouldn't commit the murder.
If I have a gun, and a 6'3" athletic thug has a gun, it is harder for him to murder me than if I am unarmed and he has a baseball bat, for the simple reason that I have an equal opportunity to defend myself.
