I'm an american gun owner although I do not like saying too much about this on a public forum for my own safety. I frequently carry a handgun (.357 magnum revolver). As far as me, I carry a gun for the following reasons:
1). To protect myself in case I needed it. It's better to have it and not need it then need it and not have it. I also generally carry pepper spray and that to me would be my go to weapon if needed.
I own guns in general for the following reasons:
1). To protect myself against criminals.
2). To protect myself in the event of a natural disaster which required me to abandon my home of where myself and my home were at risk.
3). In the event of public uprising or a sign of civil disobedience (although it is my fondest hope that it never happens)
4). To protect myself in the event of war/invasion/something bad like that (hopefully this never happens either)
5). Target shooting. I love target shooting with my rifles. It's fun.
I always advocate that if someone wants to carry a handgun that they get the proper training before they carry and understand gun safety. Putting on a handgun on one's person is a big responsibility and with it means that I will be held to a higher standard and I am okay with that. I have literally spent hours and hours in classroom time listening to and understanding the laws involving carrying, use of deadly force, etc. Some of the instructors are the same people who teach the police in the use of deadly force. But just knowing the laws is not enough. I invested further in scenario training. This is where I go out and they do real situations where I would have to respond quickly, like a car jacking, a shooting at the mall, etc. That training was quite eye opening to find one's self jumped with a knife to the throat.
I understand that such things are not for everyone. I get it. In my case, I like to have a fighting chance at survival if something did go down. I don't want to be in a dark alley with some giant brute of a man who discovers I used to be a a different person a long time ago and decides he wants to slaughter me and be defenseless in that situation. That doesn't mean I put myself deliberately in those types of circumstances just because I want to draw a gun on someone. Quite the opposite.
The training also teaches that de-escalating a situation is always the best route. There is no harm in running away. There is no way I could out fight 5 guys hell bent on my destruction, heck I couldn't out fight 1. So I carry for the same reason every woman who carries does, self protection against rape and violent crime.
I have even been toying with the idea of getting my FFL license and maybe investing in guns, since many are very collectible. FFL licenses allows me the ability to own a whole different category of weapons including machine guns.
As for the second amendment I always wondered about the clumsy wording and thought it was weird myself. In my own research I discovered that the founders of the country mirrored this right after british common law after an event that happened where catholics were disarmed against protestants, who were later disarmed by the catholics. Yes there were actual laws that said if one was a protestant they could not own a gun. The insanity of having whole groups of people disarmed is why the founders enshrined it and wrote it the way they did. Every armed citizen, including me, is a potential soldier if needed, or in peace another citizen ready to take up arms if needed. Today I totally get it. I can have all the other freedoms in the world, but if I am bleeding out in a dark alley from a vicious criminal, my freedom of speech or any other freedom is worthless if I am unable to defend my own life.
Past supreme court decisions like cruikshank were used as part of racist decisions (the infamous jim crow laws) handed down by the court after the civil war in order to deny blacks from having guns at all. This had the same effect of disarming a whole group of people like catholics vs protestants. It was not until recently (the Heller and McDonald decisions) that the court finally addressed the fact that the founders were right all along and that being able to defend one's own life is a right even if it results in the death of a another person.
In many ways the gun control debate today does exactly that as well. In fact many state courts have relied on the cruikshank decision to justify gun control. But now that cruikshank has been relegated to the ash dump of history, the views on gun ownership and control are changing.
The problem I see is that the current system of licensing is creating haves and have nots. People like me who can "afford" lots of training get permits, and people who cannot do not get them. So now what we are going to see is that people with money will have all the guns and the poor will be left defenseless since they are unable to afford the requirements to get a license.
I maintain though that a right is a right. It's not something that can be voted away. I also feel that just because someone chooses 'not' to exercise that right they shouldn't say "doesn't matter to me, take the right away". People apathetic to gay marriage say the same thing "I'm not gay, never will be, so why do I care about gay marriage?". Therefore I would rather err on the side of people have a natural right to self defense.
I know people think that criminals should not get guns, but I have an interesting story of a neighbor who is a 30 something guy. He met a girl, they fell in love, and had a kid. Later she left him and as part of the separation filed a restraining order against him as a way of winning a custody battle. In Massachusetts it resulted in instant forfeiture of his gun license and any guns he had. Keep in mind he never hit her or laid a finger on her. He grew up with guns and went hunting with his father all his life and was an avid hunter. This girl knew exactly how to hurt him and she did. I feel sorry for him that now he is treated like scum because of this and take him to the range because I know he is still a good person who was treated badly by the system. Are there some bad people who shouldn't have guns. Sure. But not everyone who gets accused of doing a bad thing is really a bad person.
This always bring me back to the point where a right is not a right if people can just take it away from you. I support many things, in fact me personally I have a very weird collection of things I support. I support gay marriage, lgbt rights, pro-choice, help for people who need assistance, and yet at the same time I also understand that self-protection is just as equal a right and not subservient. I honestly don't know where this puts me politically. If I vote republican I might as well kiss lgbt rights and gay marriage good bye. If I vote democrat, I might as well kiss gun rights good bye. To me neither option is an option I want to choose.
