Again, yes respect your parents, but come on, you have to agree do people only get things because they need it and therefore if they don't NEED it they shouldn't get it? Because saying things like "A 16 year old kid does not need to own a gun" is like saying "A 16 year old kid does not need to own a computer". I'm not saying its the same thing, but please choose your arguments more sensibly. If you base your argument solely on need, then please be ready to prove to me that you have never in your life bought something that was not a total necessity.
Also, as far as danger, it is also dangerous to turn on a car that is literally powered by explosive force, it is dangerous to consume even a drop of alcohol which (like most things) usually impairs your judgement and can either directly or indirectly lead to your death, it is dangerous to set foot on an aircraft that is propelled by a combination of fire and precision aerodynamics to make it move. It is dangerous to smoke a cigarette which is PROVEN to eventually lead to cancer and other health issues in later life if you continue. Despite these dangers, PEOPLE STILL DO IT. Why? Because flying is almost a necessity now, because drinking is how people cope with problems or just something fun to do with friends, driving IS a necessity in modern times, and I still can't find a reason people smoke..... You cannot tell me that "These things are common practice and everyone understands the danger and accepts the risk" because if they can be trusted to accept those risks and take responsibility for what happens, then why on earth can people not make the same decisions with firearms?
Alcohol is involved in approximately 75,000 deaths per year in the united states (Source below). Firearms were involved in 32,436 deaths in 1997, which just under half as many killed, which includes law abiding citizens defending themselves with legally purchased firearms. If you're so worried about saving american lives, the first thing you should do is work on prohibition of alcohol.
And please, for all the people who come on and say little more than "guns are bad, don't get it" or "guns are dangerous, don't get it" PLEASE, unless you are willing to back this up with proof or a logical, valid argument, keep it too yourself.
