It is obvious that you don't have a clue what real Liberty is, thus have no clue what a real Libertarian is, thus don't value Liberty at all, thus making you a sellout to Humanity. Your blatherings therefore stem from nothing more than what is called a Peanut Gallery and should be treated as such.

2. If, contrary to point 1 above, everyone chooses to have a weapon, then the number of injuries due to accidents, twitchy fingers and rage would likely rise.

Quote from: http://en.wikipedia.org/wiki/Gun_politics#Switzerland

Switzerland practices universal conscription, which requires that all able-bodied male citizens keep fully automatic firearms at home in case of a call-up. Every male between the ages of 20 and 34 is considered a candidate for conscription into the military, and following a brief period of active duty will commonly be enrolled in the militia until age or an inability to serve ends his service obligation.[44] During their enrollment in the armed forces, these men are required to keep their government-issued selective fire combat rifles and semi-automatic handguns in their homes.[45] Up until September 2007, soldiers also received 50 rounds of government-issued ammunition in a sealed box for storage at home.[46] In addition to these official weapons, Swiss citizens are allowed to purchase surplus-to-inventory combat rifles, and shooting is a popular sport in all the Swiss cantons.

Think before you speak.

I suggest you think before you speak. In a libertarian society, there is no law that requires one to keep a firearm, nor is there a mandatory period in which an individual goes through training in the military. If there is no law to keep a firearm, then there is no cause for one such as yourself to dream that in your fabled libertarian society, all would choose to keep a firearm. Nor is there any reason for one such as yourself to fantasize that in fabled libertarian society, all would receive the training that one gets when enrolled in the military.

Remember, in your fantasies, your libertarian society is not Switzerland.
