It seems that gun control is one type of action censorship that is constantly upheld by a majority of people. Periodically, after particular events like mass murders, an upsurge of anti-gun rhetoric is heard. First of all, there is considerable puzzlement on my part about why guns are targeted in the first place.
Guns are products like any others, and trade for guns is the same as any other form of trade.
Guns can be used to kill, but so can bombs or penguns, and both can be easily made by individuals. I have never seen anyone argue that knives or pens should be banned, or that hands should be cut. Such a behaviour could be more understandable if the sole possible function of guns was murder, but that is far from the case. Guns can be used for hunting, self-defense, and others. The fact that people decide to use them for criminal uses does not make a product any less useful.
